Let’s check out your problem:

Rashaad is saving money and plans on making monthly contributions into an account earning an annual interest rate of 
8.4% compounded monthly. If Rashaad would like to end up with 
$75,000 after 8 years, how much does he need to contribute to the account every month, to the nearest dollar? Use the following formula to determine your answer.

A=d(((1+i)^(n)-1)/(i))

A= the future value of the account after 
n periods

d= the amount invested at the end of each period

i= the interest rate per period

n= the number of periods

Q. Rashaad is saving money and plans on making monthly contributions into an account earning an annual interest rate of 8.4% 8.4 \% compounded monthly. If Rashaad would like to end up with $75,000 \$ 75,000 after 88 years, how much does he need to contribute to the account every month, to the nearest dollar? Use the following formula to determine your answer.\newlineA=d((1+i)n1i) A=d\left(\frac{(1+i)^{n}-1}{i}\right) \newlineA= A= the future value of the account after n n periods\newlined= d= the amount invested at the end of each period\newlinei= i= the interest rate per period\newlinen= n= the number of periods\newlineAnswer:
  1. Identify Given Values: Identify the given values from the problem.\newlineAA (future value of the account) = $75,000\$75,000\newlineii (monthly interest rate) = 8.4%8.4\% annual interest rate / 1212 months = 0.7%0.7\% per month = 0.0070.007 (as a decimal)\newlinenn (total number of periods) = 88 years * 1212 months/year = $75,000\$75,00000 months\newlineNow, we can use these values in the formula provided.
  2. Substitute Values into Formula: Substitute the given values into the formula.\newlineA=d×((1+i)n1)/iA = d \times \left(\left(1 + i\right)^{n} - 1\right) / i\newline$75,000=d×((1+0.007)961)/0.007\$75,000 = d \times \left(\left(1 + 0.007\right)^{96} - 1\right) / 0.007\newlineWe need to solve for dd, which represents the monthly contribution.
  3. Calculate Inside Parentheses: Calculate the value inside the parentheses.\newline(1+0.007)961(1 + 0.007)^{96} - 1\newlineFirst, calculate (1+0.007)96(1 + 0.007)^{96}.\newline1.007962.0398981.007^{96} \approx 2.039898 (using a calculator)\newlineNow, subtract 11 from the result.\newline2.03989811.0398982.039898 - 1 \approx 1.039898
  4. Divide by Interest Rate: Divide the result by the interest rate per period.\newline1.0398980.007148.5568571\frac{1.039898}{0.007} \approx 148.5568571
  5. Solve for Monthly Contribution: Solve for dd by dividing the future value of the account by the result from Step 44.\newline$75,000/148.5568571$504.96\$75,000 / 148.5568571 \approx \$504.96\newlineRashaad needs to contribute approximately $504.96\$504.96 each month.
  6. Round Monthly Contribution: Round the monthly contribution to the nearest dollar.\newlineRashaad needs to contribute approximately $505\$505 each month when rounded to the nearest dollar.
