Answer:
$69,378.96
Explanation:
The first step is to determine the future value of Jill's balance
FV = P (1 + r)^n
FV = Future value
P = Present value
R = interest rate
N = number of years
$866,000(1.09)^8 = $1,725,559.25
the second step is to determine the future value of the balance in Bob's account
$482,000(1.09)^8 = $960,415.19
The difference between Jill and Bob's future value amount is 765,144.06. this has to be the future value of bob's yearly savings
yearly savings = 765,144.06. / annuity factor
Annuity factor = {[(1+r)^n] - 1} / r
(1.09^8 - 1) / 0.09 = 11.028474
765,144.06. / 11.028474 = $69,378.96
