Answer: $3,286.47
Explanation:
Find the future value of the annuity after 10 years.
Number of periods = 10 * 12 months = 120 months
Interest = 3.2% / 12 = 3.2/12%
Future value of annuity = Annuity * ( (1 + rate)^ number of periods- 1) / rate
= 155 * ( ( 1 + 3.2%/12) ¹²⁰- 1) / 3.2%/12
= $21,886.47
The find the amount that the money would have come to without being invested:
= 155 * 120 months
= $18,600
Interest is:
= 21,886.47 - 18,600
= $3,286.47
