Let’s check out your problem:

Charlotte is saving money and plans on making monthly contributions into an account earning an annual interest rate of 
3% compounded monthly. If Charlotte would like to end up with 
$61,000 after 9 years, how much does she 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. Charlotte is saving money and plans on making monthly contributions into an account earning an annual interest rate of 3% 3 \% compounded monthly. If Charlotte would like to end up with $61,000 \$ 61,000 after 99 years, how much does she 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) = $61,000\$61,000\newlinenn (number of periods) = 99 years * 1212 months/year = 108108 months\newlineii (interest rate per period) = 3%3\% per year / 1212 months = $61,000\$61,00000
  2. Substitute Values into Formula: Substitute the given values into the formula.\newlineA=d×((1+i)n1i)A = d \times \left(\frac{(1 + i)^{n} - 1}{i}\right)\newline$61,000=d×((1+0.03/12)10810.03/12)\$61,000 = d \times \left(\frac{(1 + 0.03/12)^{108} - 1}{0.03/12}\right)
  3. Calculate Value Inside Parentheses: Calculate the value inside the parentheses (1+i)n(1 + i)^{n}.(1+0.0312)108=(1+0.0025)108(1 + \frac{0.03}{12})^{108} = (1 + 0.0025)^{108}
  4. Calculate Value of (1+i)n(1 + i)^{n}: Calculate the value of (1+i)n(1 + i)^{n}.(1+0.0025)1081.349858807576003(1 + 0.0025)^{108} \approx 1.349858807576003
  5. Calculate Numerator of Formula: Calculate the numerator of the formula (((1+i)n1)(((1 + i)^{n} - 1). 1.34985880757600310.3498588075760031.349858807576003 - 1 \approx 0.349858807576003
  6. Calculate Denominator of Formula: Calculate the denominator of the formula (i). 0.0312=0.0025\frac{0.03}{12} = 0.0025
  7. Calculate Entire Fraction: Calculate the entire fraction of the formula ((1+i)n1i)\left(\frac{(1 + i)^{n} - 1}{i}\right). 0.3498588075760030.0025139.9435230304012\frac{0.349858807576003}{0.0025} \approx 139.9435230304012
  8. Solve for d: Solve for d (the amount invested at the end of each period).\newline$61,000=d×139.9435230304012\$61,000 = d \times 139.9435230304012\newlined=$61,000139.9435230304012d = \frac{\$61,000}{139.9435230304012}
  9. Calculate Value of d: Calculate the value of d.\newlined$61,000/139.9435230304012$435.62d \approx \$61,000 / 139.9435230304012 \approx \$435.62
