Let’s check out your problem:

Bo deposits 
$490 every year into an account earning an annual interest rate of 
5.3% compounded annually. How much would he have in the account after 3 years, 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. Bo deposits $490 \$ 490 every year into an account earning an annual interest rate of 5.3% 5.3 \% compounded annually. How much would he have in the account after 33 years, 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 variables and amounts: Identify the variables from the problem to use in the formula.\newlineWe have:\newlined=$490d = \$490 (the amount invested at the end of each period)\newlinei=5.3%i = 5.3\% or 0.0530.053 (the interest rate per period)\newlinen=3n = 3 (the number of periods)
  2. Convert interest rate to decimal: Convert the interest rate from a percentage to a decimal. i=5.3%=5.3100=0.053i = 5.3\% = \frac{5.3}{100} = 0.053
  3. Plug values into formula: Plug the values into the formula to calculate the future value of the account.\newlineA=d×((1+i)n1i)A = d \times \left(\frac{(1 + i)^n - 1}{i}\right)\newlineA=490×((1+0.053)310.053)A = 490 \times \left(\frac{(1 + 0.053)^3 - 1}{0.053}\right)
  4. Calculate value inside parentheses: Calculate the value inside the parentheses.\newline(1+i)n=(1+0.053)3(1 + i)^n = (1 + 0.053)^3\newline(1+i)n=1.0533(1 + i)^n = 1.053^3\newline(1+i)n1.053×1.053×1.053(1 + i)^n \approx 1.053 \times 1.053 \times 1.053\newline(1+i)n1.162727(1 + i)^n \approx 1.162727
  5. Subtract one from result: Subtract 11 from the result obtained in Step 44.\newline(1+i)n11.1627271(1 + i)^n - 1 \approx 1.162727 - 1\newline(1+i)n10.162727(1 + i)^n - 1 \approx 0.162727
  6. Divide by interest rate: Divide the result from Step 55 by the interest rate ii.(1+i)n1i0.1627270.053\frac{(1 + i)^n - 1}{i} \approx \frac{0.162727}{0.053}(1+i)n1i3.071075\frac{(1 + i)^n - 1}{i} \approx 3.071075
  7. Multiply by amount deposited: Multiply the result from Step 66 by the amount deposited at the end of each period dd.A490×3.071075A \approx 490 \times 3.071075A1504.82675A \approx 1504.82675
  8. Round to nearest dollar: Round the result to the nearest dollar. A$1505A \approx \$1505
