a. $1,916.00

b. $‭30,656‬

c. $‭7,617‬

Explanation:

a. As they are depositing a set amount every 6 months, this is an annuity. The $36,273 is the future value of the annuity in 8 years.

n = 8 years * 6 = 16 semi annual periods

rate = 4.4/ 2 = 2.2% every 6 months

Future value = Amount * (([1 + i]^n) - 1 )/i

36,273 = Amount * (([1 + 2.2%]^16) - 1 )/2.2%

36,273 = Amount * 18.931485

Amount = 36,273/18.931485

= $1,916.00

b. Total amount deposited

= 16 * 1,916

= $‭30,656‬

c. Total amount of interest earned;

= Amount in fund - Total deposited

= 38,273 - 30,656

= $‭7,617‬
