Q. Ayden deposits $290 every month into an account earning a monthly interest rate of 0.7%. How much would he have in the account after 13 years, 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 variables: Identify the variables from the problem.We are given:Monthly deposit d = $290Monthly interest rate i = 0.7% or 0.007 (as a decimal)Number of years = 13Number of periods n = 13 years ∗12 months/year = $2900 months
Convert interest rate: Convert the interest rate to decimal form. 0.7% as a decimal is 0.7/100=0.007
Calculate periods: Calculate the number of periods.Since Ayden deposits monthly and we are looking at a 13-year period, we multiply the number of years by the number of months in a year.n=13 years×12 months/year=156 months
Use formula for future value: Use the formula to calculate the future value of the account.A=d×(i(1+i)n−1)A=$(290)×(0.007(1+0.007)156−1)
Calculate future value: Calculate the future value using the values from the previous steps.A=($)290×(0.007(1+0.007)156−1)A=($)290×(0.007(1.007)156−1)
Perform calculations: Perform the calculations inside the parentheses first.(1.007)156−1
Calculate exponentiation: Calculate the exponentiation part of the formula.(1.007)156≈2.03009 (rounded to five decimal places for simplicity)
Subtract from result: Subtract 1 from the result of the exponentiation.2.03009−1≈1.03009
Divide by interest rate: Divide the result by the interest rate.1.03009/0.007≈147.15571
Multiply by deposit amount: Multiply the result by the monthly deposit amount.A=($)290×147.15571A≈($)42675.1559
Round final answer: Round the final answer to the nearest dollar.A≈$(42675) (to the nearest dollar)
