Answer
Explanation:
Step1: Convert annual interest rate to monthly
The annual interest rate is 6%. To get the monthly interest rate $r$, divide by 12. So $r=\frac{6%}{12}=0.005$.
Step2: Calculate interest on 86th payment
The interest portion of a loan - payment is calculated by multiplying the outstanding principal $P$ by the monthly interest rate. Here, $P = 119556$ and $r=0.005$. The interest $I$ is $I = P\times r$. $I=119556\times0.005 = 597.78$
Answer:
$597.78$
