To find out how much more Tommy's account will be worth after 25 years, we need to calculate the future value of his account after 25 years at a 7.6% annual interest rate.

We can use the formula:

FV = PV x (1 + r)^n

where FV is the future value, PV is the present value, r is the annual interest rate, and n is the number of years.

Here, PV = $55,500 (annual contribution) x 25 (years) = $1,387,500. r = 7.6%, and n = 25.

So,FV = $1,387,500 x (1 + 0.076)^25= $186,514.

To find out how much John must contribute annually to retire at the same time as Tommy, we need to calculate the present value of his contributions and compare it to Tommy's account balance after 25 years, which is $186,514.

We can use the formula:PV = FV / (1 + r)^n

where PV is the present value, FV is the future value, r is the annual interest rate, and n is the number of years.

Here, FV = $1,500,000, r = 7.6%, and n = 25.

So,PV = $1,500,000 / (1 + 0.076)^25= $335,131.

John's present value after 25 years is $335,131.

He needs to contribute an additional amount to reach the goal of $1,500,000.

So,John's annual contribution = (goal - present value) / [(1 + r)^n - 1]= ($1,500,000 - $335,131) / [(1 + 0.076)^25 - 1]= $11,695.

To find out how long it will take John to reach the goal of $1,500,000, we can use the formula: n = log(FV/PV) / log(1 + r)

where FV is the future value, PV is the present value, r is the annual interest rate, and n is the number of years. Here, FV = $1,500,000, PV = $55,500 (annual contribution), r = 7.6%.

So,n = log($1,500,000 / $55,500) / log(1 + 0.076)= 36.95 years. years

.To find out how much sooner Tommy can retire, we need to calculate the number of years it will take him to reach $1,500,000 at a 9.6% annual interest rate.

We can use the formula:n = log(FV/PV) / log(1 + r)where FV is the future value, PV is the present value, r is the annual interest rate, and n is the number of years.

Here, FV = $1,500,000, PV = $55,500 (annual contribution), r = 9.6%.

So,n = log($1,500,000 / $55,500) / log(1 + 0.096)= 32.95 years. Tommy will retire 5 years sooner than John (37 years - 32 years = 5 years).

The Engel curve for good q2​, given Sally's utility function U=6(q1​)0.5+q2​, is Y= (6(q1​)0.5) / p2​.

To derive the Engel curve, we need to find the relationship between income (Y) and the quantity consumed of good q2​. In Sally's utility function, the first term represents the utility she receives from consuming q1​, and the second term represents the utility she receives from consuming q2​.

To find the Engel curve for q2​, we need to hold q1​ constant and vary Y. We can do this by solving the utility function for q1​ and substituting it into the income equation.

Rearranging the utility function, we have (q1​)0.5 = (U - q2​) / 6. Substituting this into the income equation Y = p1​q1​ + p2​q2​, we get Y = p1​(U - q2​) / 6 + p2​q2​.

Simplifying further, we have Y = (p1​U - p1​q2​) / 6 + p2​q2​.

Rearranging the terms, we get Y = (p1​U + 6p2​q2​ - p1​q2​) / 6. Finally, we can factor out q2​ from the numerator to obtain Y = (6(q1​)0.5) / p2​.

Therefore, the Engel curve for good q2​ is Y = (6(q1​)0.5) / p2​, where Y represents income, q1​ is the quantity consumed of good q1​, and p2​ is the price of good q2​.

What is linear equation ?
A linear equation is an algebraic equation that represents a straight line on a graph. It is a polynomial equation of the first degree, which means that the highest power of the variable in the equation is one. Linear equations can be written in the form

\(y = mx + b\)

where y and x are variables,

m is the slope of the line

b is the y-intercept.

Step-by-step explanation:

Given linear equation is 5(x+1)-x=3(x-1)+7
To solve the equation, we can simplify and collect like terms on each side:
5(x+1) - x = 3(x-1) + 7

5x + 5 - x = 3x - 3 + 7 // Distribute the 5 and 3

4x + 5 = 3x + 4 // Simplify by combining like terms

x = -1 // Subtract 3x from both sides, then subtract 5 from both sides

Therefore, x = -1 is the solution to the equation.

The base case in the given pseudocode is factor(0).

The pseudocode is using recursion to find the factorial of a number. In each recursive call, the function is subtracting 1 from the given number (n - 1) and then multiplies it with the result of the recursive call for n - 1. The base case is the condition that stops the recursion and provides a result.

In this case, the base case is a factor(0). When the input number reaches 0, the recursion stops, and the function returns 1. This is because the factorial of 0 is defined as 1.

So, when the base case is reached, the recursion unwinds, and the factorial value is calculated by multiplying the current number (n) with the result of the previous recursive call (factor(n - 1)).

Step-by-step explanation:

Any t statistic greater than 2.947 would be considered statistically significant at the 0.005 level, leading to the rejection of the null hypothesis H0: μ = 0 in favor of the alternative hypothesis Ha: μ > 0.

To determine the values of the t statistic that are statistically significant at alpha = 0.005 level when testing H0: μ = 0 against Ha: μ > 0 based on an SRS of 16 observations from a Normal population, you should follow these steps:

1. Determine the degrees of freedom (df): Since you have an SRS of 16 observations, the df = 16 - 1 = 15.
2. Identify the alpha level: In this case, alpha = 0.005.
3. Use a t-distribution table or software to find the critical t value corresponding to the given alpha level and df: For df = 15 and a one-tailed test with alpha = 0.005, the critical t value is approximately 2.947.

When Solver is unable to find a solution to a problem, it can be an indication of various issues. One possible cause is that the problem may be too complex for Solver to solve within the given constraints.

In such cases, it may be necessary to adjust the problem parameters or seek alternative solutions. Another possible cause of Solver's inability to find a solution could be due to incorrect input data. This can lead to inconsistent or contradictory constraints, making it impossible for Solver to arrive at a feasible solution. Lastly, Solver may fail to find a solution due to numerical errors or limitations in the algorithm used. These issues can arise when dealing with large datasets or highly non-linear problems. In any case, when Solver is unable to find a solution, it is important to carefully examine the problem and its parameters, and consider alternative approaches. Sometimes, a small adjustment to the input data or constraints can make all the difference in arriving at a successful solution.  In such cases, Solver may struggle to find an accurate or optimal solution. Ill-conditioned problems typically involve numerical instability or poor scaling, while infeasible problems occur when the given constraints cannot be satisfied simultaneously. It is crucial to analyze and refine the problem to enable Solver to find a viable solution effectively. When there is a problem with Solver being unable to find a solution, it often indicates the presence of a(n) ill-conditioned or infeasible problem.

The candy store will use 103 grams of sugar in 10 hours.

To find out how many grams of sugar the store will use in 10 hours, we can simply multiply the amount of sugar used in one hour (10.3 grams) by the number of hours (10).

To solve the problem, we use a simple multiplication formula: the amount used per hour (10.3 grams) multiplied by the number of hours (10) to find the total amount of sugar used in 10 hours.

We can interpret this problem using a rate equation: the rate of sugar usage is 10.3 grams/hour, and the time period is 10 hours. Multiplying the rate by the time gives the total amount of sugar used.

So the calculation would be:

10.3 grams/hour x 10 hours = 103 grams

Therefore, the candy store will use 103 grams of sugar in 10 hours.

Answer:

25 t-shirts and 35 hats were sold

Step-by-step explanation:

Here, we want to calculate the number of hats and the number of t-shirts sold.

Let the number of hats be h and the number of t-shirts be t

The sum of both is 60;

Mathematically;

h + t = 60 •••••••••••(i)

The total revenue from selling h hats at $12 per one is 12 * h = $12h

The total revenue from selling t t-shirts at $18 per one is 18 * t = $18t

So the addition of this gives the total;

12h + 18t = 870 ••••••••(ii)

From i, h = 60-t; substitute this into ii

12(60-t) + 18t = 870

720 -12t + 18t = 870

720 + 6t = 870

6t = 870 -720

6t = 150

t = 150/6

t = 25
