Step-by-step explanation:

1) Popcorn unit price: 17.57/7 = $2.51

2.51 x 3 = 7.53

Three bags of popcorn would cost $7.53.

2) Old games unit price: 73.10/5 = 14.62

14.62 x 6 = 87.72

If they sold six games they would've made $87.72.

3) Lollipop unit price: 20.51/7 = %2.93

2.39 x 4 = 11.72

Four lollipops would cost $11.72

4) Hotdogs unit price: 82.86/3 = $27.42

Hamburgers unit price: 55.12/2 $27.56

Hotdogs have the lower unit price. $27.42 < $27.56

5) Packs of paper unit price: 12.74/7 = $1.82

1.82 x 2 = 3.64

Two packs of paper would cost $3.64

6) Pair of shoes unit price: 49.32/4 = $12.33

12.33 x 6 = $73.98

Six pairs of shoes would cost $73.98

7) Brand A unit price: 71.28/6 = $11.88

Brand B unit price: 59.15/5 = $11.83

Brand B has the cheaper price. $11.83 < $11.88

8) Pounds of seeds unit price: 37.62/2 = $18.81

18.81 x 6 = $112.86

Six pounds of seeds would cost $112.86

9) Red Grapes unit price: .82

Green Grapes unit price: .84

Green grapes are more expensive. .84 > .82

10) Book Store unit price : 21.69/3 = $7.23

Online unit price: 14.28/2 = $7.14

Online has a lower unit price. $7.14 < $7.23

Answer:

4/30

Step-by-step explanation:

So first of all you want to convert both fractions so that they have a common denominator (30)

-1/6= -5/30

3/10=9/30

Next, you want to picture a number line in your head. Now picture -5/30 on the number line, and move 9/30 steps. Bringing you to 4/30.

How I did that:

9-5 (negative amount)=4 (amount you have after getting rid of the 5 steps that took you to 0)

Step-by-step explanation:

When multiplied we get 52,145.83413. If we count, we see that five numbers are to the right of the decimal place.

Isolate the variable by dividing each side by factors that don't contain the variable.

Inequality Form:

x<4

The solution to the given inequality 3x - 3 < 9 is;

x < 4

We are given the inequality;

3x - 3 < 9

Using addition property of equality, add 3 to both sides to get;

3x - 3 + 3 < 9 + 3

3x < 12

Using division property of equality, divide both sides by 3 to get;

3x/3 < 12/3

x < 4

Step-by-step explanation:

i don't really know how to explain it, sorry.

Answer:

y = 7x - 16

Step-by-step explanation:

slope = y2-y1/x2-x1

slope = 12 - (-9)/4-1

slope = 7

Y-intercept = -9-7

Y-intercept = -16

Y = 7x-16

Answer: 45

100% of 18 = 18

50% of 18 = 9

18 + 18 = 36 = 200%

36 + 9 = 45 = 250%

:)

Answer: 45

Step-by-step explanation:

To find a percentage of a number, like what we're being asked to do, you multiply the number ( 18 in this case ) with the decimal form of the percentage. So, since we know 100% is equal to 1, 150% is equal to 1.5 and so on, 250% must be equal to 2.5. Since we know this, we now do:

2.5 x 18 = 45.

Step-by-step explanation:

Answer:

Step-by-step explanation:

1 and 2

1 because indeed you can't divide -20.2 by zero to get y

2 because the inequality is basically a false situation.

area square: 9in×9in = 81in

area triangle: [9in×(13in-9in)]/2

= (9in×4in)/2

=36in/2

=18in

green area: 81in+ 18in= 99in

Step-by-step explanation:

A=9×9

=18sqcm

B=1/2×9×4

=36/2

=18sqcm

hence area of shape= 18+18

=36sqcm

Answer:

(1.5, 4.5 ) and (- 1.5, - 4.5 )

Step-by-step explanation:

Under a reflection in the x- axis

a point (x, y ) → (x, - y ) , then

(1.5, - 4.5 ) → (1.5, 4.5 )

Under a reflection in the y- axis

a point (x, y ) → (- x, y ) , then

(1.5, - 4.5 ) → (- 1.5, - 4.5 )

If x- axis then y- axis

(1.5, - 4.5 ) → (1.5, 4.5 ) → (- 1.5, 4.5 )

Answer:

Penny will be able to catch up 20 minutes after Penny starts hiking on the trail.

Step-by-step explanation:

Answer:

To find the correct selling price, we need to first find the cost of the item plus the markup. We can do this by multiplying the cost of the item by the markup percentage: $6 * 67% = $4.02. However, since the question asks us to round to the nearest dollar, we can round this number down to $4.

Therefore, the correct selling price is $4.

The manager's likely error was that they set the selling price at the cost (option C).

Step-by-step explanation:

The correct selling price is $10 and the manager set the selling price at the markup so option (A) is correct.

The percentage is defined as a given amount in every hundred. It is a fraction with 100 as the denominator percentage is represented by the one symbol %.

The percentage is also called the indicating hundredths. Thus, 2% is two-hundredth, which means 2%=2/100=0.02.

As per the given,

Cost of item = $6

Markup = 67%

67% of $6 ⇒ 0.67 x 6 = $4.02

Add the markup in the cost = $6 + $4.02 = $10.02

Round to nearest dollars = $10.2 ≈ $10.

The manager put $4 which is a markup instant of the selling price of $10.

Hence "The correct selling price is $10 and the manager set the selling price at the markup".

Answer:

$375 ($75 more dollars)

Step-by-step explanation:

25% of 300 is 75, so, 300+75 is 375.

Answer:

\(\huge\boxed{$75}\)$75

Step-by-step explanation:

Joni currently earns $300 per week (given)

To find how much more she will earn each week, write an expression adding the original pay and the raise amount.

$300 + 25%

Find 25 as a decimal for multiplication

25%  = 25/100 = 0.25

Write an expression to represent the scenario

Expression example 1:

$300 + 0.25(300)

This expression adds the original pay and the new raise together.

Expression example 2:

$300 (1.25)

This expression already takes the new pay into account by finding 125% of the original pay.

Simplify both expressions

Expression 1:

$300 + 0.25(300)

$300 + $75

$375

Expression 2:

$300 (1.25)

$375

Both expressions represent the same scenario and therefore come out to the same result. Now that we know how much Joni made after the raise, we need to find how much more money she will earn in a week with the following equation.

New amount - original amount = amount increase

Substitute known values into the equation

$375 - $300

Simplify

$75

Joni will earn $75 more each week.

The function for the points are  y = -15x - 5

From the information given, we have that;

The points are;

(1/3,0) (-2 3/4,0) and (0,-5)

Using the point-slope form of a linear equation, we have;

y - y₁ = m(x - x₁)

Such that;

Using (1/3, 0) and (0, -5), we have that the slope is;

m = (0 - (-5))/0 -1/3)

expand the bracket

= 5 / (-1/3)

= -15

Now, take any of the given points and substitute the values

Using (1/3, 0), we get;

y - 0 = -15(x - 1/3).

y = -15x - 5.

The function for the points solved by  (1/3,0) (-2 3/4,0) and (0,-5) solved by point slope form is \(a=-15b-5\)

We have given the points:

(1/3,0) (-2 3/4,0) and (0,-5)

Using the formula of linear equation

\(a-\)\(a_{1}\)\(=x[b-b_{1}]\)                                                          

Where we will consider (1/3,0) = \(a-a_{1}\) and (0,-5) = \(b-b_{1}\)

that is 1/3 = \(a\), 0 = \(a_{1}\) and

0 = \(b\), -5 = \(b_{1}\)

\(x\) refers to the slope of line (take any variable)

Now for finding the value of \(x\),

\(x=a-a_{1}/b-b_{1}\)

inserting the values,

\(x=[0-[-5]]/[0-1/3]\\x= -15\)

Substitute the value of \(x\) in the equation

\(a-0=-15[b-1/3]\)

By simplifying the equation, we get

\(a=-15b-5\)
