Savannah deposits 
$360 every month into an account earning a monthly interest rate of 
0.65%. How much would she have in the account after 8 months, to the nearest dollar? Use the following formula to determine your answer.

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

Q. Savannah deposits $360 \$ 360 every month into an account earning a monthly interest rate of 0.65% 0.65 \% . How much would she have in the account after 88 months, 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.\newlineWe are given:\newlinedd (the amount invested at the end of each period) = $360\$360\newlineii (the interest rate per period) = 0.65%0.65\% or 0.00650.0065 in decimal form\newlinenn (the number of periods) = 88 months\newlineWe will use these values in the formula A=d((1+i)n1i)A=d\left(\frac{(1+i)^{n}-1}{i}\right) to find AA, the future value of the account.
  2. Convert Interest Rate: Convert the interest rate from a percentage to a decimal. 0.65%0.65\% as a decimal is 0.00650.0065.
  3. Substitute Values: Substitute the values into the formula.\newlineA=360×((1+0.0065)81)/0.0065A = 360 \times \left(\left(1 + 0.0065\right)^{8} - 1\right) / 0.0065
  4. Calculate (1+i)n(1 + i)^n: Calculate the value inside the parentheses (1+i)n(1 + i)^n.(1+0.0065)8=1.00658(1 + 0.0065)^8 = 1.0065^8
  5. Calculate (1+i)n(1 + i)^n: Calculate (1+i)n(1 + i)^n using a calculator.1.006581.05271.0065^8 \approx 1.0527
  6. Subtract 11: Subtract 11 from the result of step 55.\newline1.05271=0.05271.0527 - 1 = 0.0527
  7. Divide by ii: Divide the result of step 66 by ii.0.05270.00658.1077\frac{0.0527}{0.0065} \approx 8.1077
  8. Multiply by dd: Multiply the result of step 77 by dd.360×8.10772918.772360 \times 8.1077 \approx 2918.772
  9. Round to Nearest Dollar: Round the result to the nearest dollar. The future value of the account, rounded to the nearest dollar, is approximately $2919\$2919.
