Q. Emily is saving money and plans on making monthly contributions into an account earning a monthly interest rate of 0.375%. If Emily would like to end up with $4,000 after 13 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 Given Values: Identify the given values from the problem.A (future value of the account) = $4,000i (interest rate per period) = 0.375% per month or 0.00375 in decimal formn (number of periods) = 13 monthsWe need to find d (the amount invested at the end of each period).
Convert Interest Rate: Convert the interest rate from a percentage to a decimal. i=0.375%=1000.375=0.00375
Substitute Values into Formula: Substitute the values into the formula.A=d×(i(1+i)n−1)$4,000=d×(0.00375(1+0.00375)13−1)
Calculate Value Inside Parentheses: Calculate the value inside the parentheses.(1+0.00375)13−1= (1.00375)13−1= 1.05016−1= 0.05016
Divide by Interest Rate: Divide the result by the interest rate.0.05016/0.00375= 13.376
Solve for d: Solve for d by dividing the future value A by the result from Step 5.d=13.376$4,000d≈299.11
Round Monthly Contribution: Round the monthly contribution to the nearest dollar. d≈$299.11Emily needs to contribute approximately $299 per month.
