Your factory makes tires. It costs you $175,000 to pay for the lease each year. The cost to make a tire includes labor and materials, but comes to $53 per tire.
A) Write the equation of the line that represents your annual costs based on how many tires you make. Be sure to label you variables.
B) How many tires do you need to sell to break even if you sell them for $89 per tire.
In economics, business, and notably cost accounting, the break-even point (BEP) is the point at which total costs and total revenues are equal, or "even" and we need to sell a total of 1967 tires at the price of $89 to break even.
What is break even?
The break-even point (BEP) is the point at which total costs and total revenues are equal, or "even," in economics, business, and particularly cost accounting.
Although opportunity costs have been paid and capital has received the risk-adjusted, projected return, there is no net loss or gain, and one has "broken even."
In other words, all necessary expenses are covered, and neither a profit nor a loss is realized.
So, for the break-even:
= 175000/89
= 1,966.29
Rounding off: 1967
Therefore, we need to sell a total of 1967 tires at the price of $89 to break even.

On the last chemistry exams a student scored 83, 89, and 92. What score must the student earn on the next exam to have an average of at least 90?
In order to get an average of 90, the student needs to get a score of 96.
The average can be found by summing up all the numbers in a data set and then dividing it by the number of characters in that dataset.
Assuming the average is 90, and that the score the student needs to get is x, the formula would be:
Average = Sum of scores / Number of scores
90 = (83 + 89 + 92 + x) / 4
90 x 4 = 264 + x
x = 360 - 264
x = 96
The student needs to get a score of 96 on the last exam.

I need help with task 2!!Cab companies often charge a flat fee for picking someone up and then charge an additional fee per mile driven. Pick a U.S. city and research the rates of twodifferent cab companies in that city. Find companies that charge different amounts per mile and have different flat fees. If you have trouble finding this information for two companies, you can make up what you think would be reasonable prices for a cab's flat rate and a cab's rate per mile.
Let's take as an example a flat fare of $2.5 and $0.5 per mile. If we want to calculate the total cost for 0 miles, we need to multiply the cost per mile by the number of miles and add the result to the flat fare, we get:
\(C_0=2.5+0.5(0)=2.5\)Therefore, the cost for 0 miles is $2.5.
The cost for 1 mile is:
\(C_1=2.5+(0.5)(1)=3\)Therefore, the cost for 1 mile is $3.
The cost for 2 miles is:
\(C_2=2.5+(0.5)(2)=3.5\)Therefore, the cost per 3 miles is $3.5. We continue like this for the 3, 4, and 5 miles and we get:
\(\begin{gathered} C_3=2.5+(0.5)(3)=4 \\ C_4=2.5+(0.5)(4)=4.5 \\ C_5=2.5+(0.5)(5)=5 \end{gathered}\)With these values, we can fill the table.
Part a: An equation in slope-intercept form for the cost is given when we set "x" as the number of miles and use the same procedure as before, but for "x" miles:
\(C_x=2.5+0.5x\)This is a slope-intercept form of a line equation. This form is preferable because it is easier to use for calculating the total cost by simply replacing the values of "x" and solving the operations.
Part c A line equation in slope-intercept form is:
\(y=mx+b\)Where "m" is the slope and "b" is the y-intercept. In this case, the slope is 0.5 and it represents the cost per mile.
Lana works as an accountant and ears $78,832 per year. What is Lana’s approximate weekly earnings
Answer:
$1516

$78,832 / 52 weeks = $1516 per week
-If Lana worked every week of the year with no vacation with only weekends as a break.
Answer:
Lana earns $1,511.85
Step-by-step explanation:
There are 52.1429 weeks in a year, you would divide the amount of money ($78,832) by the amount of weeks in a year (52.1429).
$78,832÷52.1429=1511.845333
Which rounded equals $1,511.85
a)while wages have increased, spending power has mostly remained the same since 2000
b) as wages go up, so does spending power
c) the spending power of men is less than the spending power of the overall population
d) the wages of women have increased faster than the wages of men
Based on the information, the answer is A). While wages have increased, spending power has mostly remained the same since 2000.
How to explain the informationThe fact that the cost of living has also increased, eating up much of the gains from wage growth. In addition, many Americans are now working multiple jobs, which can leave them with less time and energy to spend money on discretionary items.
According to the Bureau of Labor Statistics, the average hourly wage for all workers in the United States increased by 16.3% between 2000 and 2021. However, the Consumer Price Index (CPI), which measures the cost of a basket of goods and services, increased by 26.5% over the same period. This means that the purchasing power of the average worker has actually declined by 10.2% since 2000.
The rise of the gig economy has also contributed to the decline in spending power. Many Americans are now working multiple jobs, often in low-wage industries such as food service and retail.

Answer: $130 money did Brenda and Hazel have all together before buying decorations and snacks.
Here, we have,
You want to know Brenda and Hazel's combined money when the ratio of their remaining balances is 1 : 4 after Brenda spent $58 and Hazel spent $37. They had the same amount to start with.
Setup
Let x represent the total amount the two women started with. Then x/2 is the amount each began with, and their fnal balance ratio is ...
(x/2 -58) : (x/2 -37) = 1 : 4
Solution
Cross-multiplying gives ...
4(x/2 -58) = (x/2 -37)
2x -232 = x/2 -37 . . . . . . eliminate parentheses
3/2x = 195 . . . . . . . . . . . . add 232-x/2
x = (2/3)(195) = 130 . . . . . multiply by 2/3
Brenda and Hazel had $130 altogether before their purchases.
Alternate solution
The difference in their spending is $58 -37 = $21.
This is the same as the difference in their final balances.
That difference is 4-1 = 3 "ratio units", so each of those ratio units is $21/3 = $7.
Their ending total is 1+4 = 5 ratio units, or $35.
The total they started with is $58 +37 +35 = $130.

Step-by-step explanation:
There are six pizzas there are 36 players on the team. If each member has one slice and each pizza has eight slices how much pizza in fraction form will be left over.
There will be 12 slices of pizza left over, which can be expressed as 3/2 or 1 1/2 slices in fraction form.
To find out how much pizza will be left over, we need to calculate the total number of slices available and subtract the number of slices consumed by the players.
Given that there are six pizzas and each pizza has eight slices, the total number of slices available is 6 pizzas * 8 slices/pizza = 48 slices.
Since there are 36 players on the team, and each player has one slice, the total number of slices consumed is 36 slices.
To determine the remaining slices, we subtract the consumed slices from the total available slices: 48 slices - 36 slices = 12 slices.
Therefore, there will be 12 slices of pizza left over.
To express this as a fraction, we can write it as 12/1, which simplifies to 12. This means there will be 12 whole slices of pizza left over.
If you would like to express it as a fraction in its simplest form, you can write it as 12/8. By dividing both the numerator and denominator by their greatest common divisor, which is 4, we get 3/2. So, in fraction form, there will be 3/2 or 1 1/2 slices of pizza left over.

If there is a very weak correlation between two variables, then the coefficient of determination must be:
much larger than 1, if the correlation is positive
much smaller than -1, if the correlation is negative
much larger than one
None of these alternatives is correct.
If there is a very weak correlation between two variables, then the coefficient of determination must be: D. None of these alternatives is correct.
What is a weak correlation?Even though both variables tend to increase in response to one another, a weak positive correlation shows that the relationship is not very strong. On the other hand, a strong negative correlation shows a connection between the two variables, but that one increases whenever the other one decreases.
The direction of the linear relationship between x and y is indicated by the sign of the linear correlation coefficient. The linear relationship is strong when the correlation coefficient, or r, is close to 1 or 1, and weak when it is close to 0.
Since, the coefficient of determination is such that 0 < r 2 < 1, and the given options has values no values between 0 and 1. Hence, the correct option is D.
