Q. Morgan is saving money and plans on making monthly contributions into an account earning a monthly interest rate of 0.75%. If Morgan would like to end up with $99,000 after 10 years, 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 Given Values: Identify the given values from the problem.A (future value of the account) = $99,000i (monthly interest rate) = 0.75% or 0.0075 when converted to decimaln (number of periods in 10 years, with monthly contributions) = 10 years ∗12 months/year = 120 months
Plug into Formula: Plug the given values into the formula to solve for d (the amount invested at the end of each period).A=d×(i(1+i)n−1)(\newline\)$99,000=d×(0.0075(1+0.0075)120−1)
Calculate (1+i)n: Calculate the value of (1+i)n.(1+0.0075)120=(1.0075)120
Calculate ((1+i)n−1): Calculate the value of ((1+i)n−1). (1.0075)120−1
Calculate Denominator: Calculate the denominator of the formula i. 0.0075
Calculate Entire Right Side: Calculate the entire right side of the equation, which is the expression for d.d=((1.0075)120−1)/0.0075inlinelatex199,000
Compute Values: Use a calculator to compute the values.d=((1.0075)120−1)/0.0075$99,000d≈(2.039887307…−1)/0.0075$99,000d≈1.039887307…/0.0075$99,000d≈138.6516409…$99,000d≈$714.14
Round Monthly Contribution: Round the monthly contribution to the nearest dollar. d≈$(714)
