Answer:
a.$449,637
b.$408,761
Step-by-step explanation:
Future value of first payment today or first payment at year-end can be calculated by multiplying the present value by the cumulative FV factor of 10% for 19 years of an annuity due and for 19 years of ordinary annuity respectively.
Future value of first payment today = $7,990 * Cumulative FV factor at 10% for 19 years of annuity due
Future value of first payment today = $7,990 * 56.275
Future value of first payment today = $449,637
Future value of first payment at year-end = $7,990 x Cumulative FV factor at 10% for 19 years of annuity
Future value of first payment at year end = $7,990 x 51.15909
Future value of first payment at year end = $408,761
