Victoria is saving money and plans on making monthly contributions into an account earning a monthly interest rate of 0.475%. If Victoria would like to end up with $15,000 after 26 months, 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(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:
Q. Victoria is saving money and plans on making monthly contributions into an account earning a monthly interest rate of 0.475%. If Victoria would like to end up with $15,000 after 26 months, how much does she need to contribute to the account every month, to the nearest dollar? Use the following formula to determine your answer.A=d(i(1+i)n−1)A= the future value of the account after n periodsd= the amount invested at the end of each periodi= the interest rate per periodn= the number of periodsAnswer:
Identify variables: Identify the variables from the problem to use in the formula.Future value of the account, A=$(15,000)Monthly interest rate, i=0.475% or 0.00475 (as a decimal)Number of periods, n=26 monthsWe need to find the monthly contribution, d.
Plug values into formula: Plug the known values into the formula to solve for d.A=d×(i(1+i)n−1)(\newline\)$15,000=d×(0.00475(1+0.00475)26−1)
Calculate compound factor: Calculate the compound factor (1+i)n.(1+0.00475)26=(1.00475)26
Evaluate compound factor: Evaluate the compound factor.(1.00475)26≈1.13047 (rounded to five decimal places for precision)
Substitute compound factor: Substitute the compound factor back into the formula.$15,000=d×(0.004751.13047−1)
Calculate numerator: Calculate the numerator of the fraction. 1.13047−1=0.13047
Divide numerator by rate: Divide the numerator by the interest rate to find the value of the fraction.0.13047/0.00475≈27.46737 (rounded to five decimal places for precision)
Solve for d: Solve for d by dividing the future value of the account by the value of the fraction.$15,000/27.46737≈546.039 (rounded to three decimal places for precision)
Round monthly contribution: Round the monthly contribution to the nearest dollar. d≈$546 (to the nearest dollar)
