Answer:
a. $18,000
b. $16,922.18
Step-by-step explanation:
a. The parents will receive $750 every month for 2 years while the man is away.
That means $750 for 24 months.
Total = 750 * 24
= $18,000
b. Payment is monthly so interest and period have to be converted accordingly.
2 years = 24 months
6% per year = 6/12 = 0.5% a month
Present Value of annuity formula;
PV = Pmt x (1 - (1 / (1 + i)^n)) / i
= 750 * ( 1 - (1 / 1.005^24))/0.005
= 750 * 22.5629
= $16,922.18
