Answer:

a. FV = $1,000,000

rate = 9.7%

n = 40 periods

FVIFA = [(1 + 0.097)⁴⁰ - 1] / 0.097 = 407.9960231

annual savings = $1,000,000 / 407.9960231 = $2,451.00

b. FV = $1,000,000

rate = 9.7%

n = 30 periods

FVIFA = [(1 + 0.097)³⁰ - 1] / 0.097 = 155.4306295

annual savings = $1,000,000 / 155.4306295 = $6,433.74

FV = $1,000,000

rate = 9.7%

n = 20 periods

FVIFA = [(1 + 0.097)²⁰ - 1] / 0.097 = 55.35978429

annual savings = $1,000,000 / 55.35978429 = $18,063.65
