Carol Gray wants to invest a certain sum of money at the end of each year for five years. The investment will earn 7% compounded annually. At the end of five years, she will need a total of $39000 accumulated. How should she compute her required annual investment? $39000 divided by the future value of a 5-year, 7% ordinary annuity of 1. $39000 times the future value of a 5-year, 7% ordinary annuity of 1. $39000 times the present value of a 5-year, 7% ordinary annuity of 1. $39000 divided by the present value of a 5-year, 7% ordinary annuity of 1.
