Answer:
$36,800
Step-by-step explanation:
The total amount of interest expense included in the first annual principal
= Principal's balance × yearly interest rate
= $320,000 × 11.5%
= $36,800
The principal's balance after the first payment is
= $320,000 - $36,800
= $283,200
The interest expense included in the second payment is
$283,200 × 11.5%
= $32,568
