Q. Jason deposits $830 every month into an account earning an annual interest rate of 3.9% compounded monthly. How much would he have in the account after 9 months, to the nearest dollar? Use the following formula to determine your answer.A=d(i(1+i)n−1)A= the future value of the account after n periodsd= the amount invested at the end of each periodi= the interest rate per periodn= the number of periodsAnswer:
Identify Values: Identify the given values from the problem.Jason deposits $830 every month into an account, so d=$830.The annual interest rate is 3.9%, so the monthly interest rate i=12 months3.9%=0.325% per month.The number of periods n=9 months.
Convert Interest Rate: Convert the annual interest rate to a decimal to use in the formula.i=1003.9%=0.039 (annual rate in decimal)i=120.039 (monthly rate in decimal)i≈0.00325
Plug into Formula: Plug the values into the compound interest formula to calculate the future value A.A=d×((1+i)n−1)/iA=830×((1+0.00325)9−1)/0.00325
Calculate Exponent: Calculate the value inside the parentheses and the exponent.(1+0.00325)9≈1.02947
Subtract One: Continue the calculation by subtracting 1 from the result of the exponentiation.1.02947−1≈0.02947
Divide by Rate: Divide the result by the monthly interest rate i.0.02947/0.00325≈9.06769
Multiply by Deposit: Multiply the result by the monthly deposit amount d to find the future value A.A=830×9.06769A≈7526.2027
Round to Nearest Dollar: Round the future value A to the nearest dollar.A≈$(7526)
