Q. Joseph is saving money and plans on making monthly contributions into an account earning a monthly interest rate of 0.75%. If Joseph would like to end up with $259,000 after 13 years, how much does he 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) = $259,000i (monthly interest rate) = 0.75% or 0.0075 when converted to decimaln (total number of periods in months) = 13 years ∗12 months/year = 156 monthsWe will use the formula A=d(i(1+i)n−1) to find $259,0000, the monthly contribution.
Substitute Values into Formula: Substitute the given values into the formula.A=$259,000i=0.0075n=156Now, plug these values into the formula to solve for d.
Calculate Exponent: Calculate the value inside the parentheses and the exponent.First, calculate (1+i)n which is (1+0.0075)156.
Compute (1+0.0075)156: Use a calculator to compute (1+0.0075)156.(1+0.0075)156≈3.4449 (rounded to four decimal places for simplicity)
Subtract 1: Subtract 1 from the result obtained in Step 4.3.4449−1≈2.4449
Divide by i: Divide the result from Step 5 by i.0.00752.4449≈325.9867
Substitute into Formula: Substitute the result from Step 6 into the formula to solve for d. $259,000=d×325.9867 Now, solve for d by dividing both sides of the equation by 325.9867.
Calculate Monthly Contribution: Calculate the monthly contribution d. d=325.9867$259,000≈$794.55Since the question asks for the nearest dollar, we round this to $795.
