Answer

# Explanation: ## Step1: Convert annual rate to monthly rate The annual interest rate is 4% or 0.04. The monthly - interest rate $r$ is $\frac{0.04}{12}$. ## Step2: Calculate interest for 81st payment The interest portion of a loan payment is calculated by multiplying the outstanding principal $P$ by the monthly - interest rate. Here, $P = 151840$ and $r=\frac{0.04}{12}$. So the interest $I$ is $I = 151840\times\frac{0.04}{12}$. $I=\frac{151840\times0.04}{12}=\frac{6073.6}{12}\approx506.13$ # Answer: $506.13$
