Question 1194507: At the end of each year for 8 years, a corporation will deposit $12, 500 in a depreciation fund to provide
for replacement of machinery at the end of 8 years. If the fund accumulates at 8% effective, how much is in it
just after the: (a) last deposit; (b) 5th deposit?

At the end of each year for 8 years, a corporation will deposit $12,500 in a depreciation fund
to provide for replacement of machinery at the end of 8 years. If the fund accumulates
at 8% effective, how much is in it just after the:
(a) last deposit;
(b) 5th deposit?

It is a classic Ordinary Annuity saving plan. The general formula is
FV =  , (1)
where FV is the future value of the account; P is the annual payment (deposit);
r is the annual percentage rate presented as a decimal;
n is the number of deposits (= the number of years, in this case).
(a) Under given conditions, P = 12500; r = 0.08; n = 8. So, according to the formula (1),
Future value at the end of the 8-th year
FV =  = $132,957.85 (rounded).
It is the ANSWER to question (a).
(b) This time, P = 12500; r = 0.08; n = 5. So, according to the formula (1),
Future value at the end of the 5-th year
FV =  = $73,332.51 (rounded).
It is the ANSWER to question (b).
