Question

Jane and her husband deposited $500 in an account on their wedding day and each subsequent anniversary. The money was deposited in an account that pays 7 percent interest, compounded annually. How much will they have on their 25th anniversary

Answer 1

Total = 500 * ([(1 + .07)^26 -1] / .07) -500
Total = 500 * (4.8073529249 / .07) -500
Total = 500 * (68.6764703562) -500
Total = 33,838.24
