Solution:

We can use the annual compound interest formula: A = P(1 + r)^t. So we have:

A = 1200(1 + 0.1)^3

A = 1200(1.1)^3

A = 1597.2

The amount of $1597.20 is the total amount (principal plus interest) he owes, so the amount of interest he owes is 1597.2 - 1200 = $397.2, or approximately $400.

Answer: C
