Answer
# Answer:
$19.8$
# Explanation:
## Step1: Convert annual rate to monthly rate
The annual interest rate is $15\%=0.15$. The monthly - interest rate $r=\frac{0.15}{12}=0.0125$.
## Step2: Calculate interest on 11th payment
The interest on a payment is calculated based on the outstanding principal. The outstanding principal is $P = 1584$. The interest $I$ on the 11th payment is $I=P\times r$. Substitute $P = 1584$ and $r = 0.0125$ into the formula: $I=1584\times0.0125 = 19.8$.
