The monthly interest payment is calculated by multiplying the average balance by the monthly interest rate.
To find the monthly interest rate, we need to divide the annual interest rate by 12 (since there are 12 months in a year).
24% annual interest rate / 12 months = 2% monthly interest rate
Now that we have the monthly interest rate, we can calculate the monthly interest payment by multiplying the average balance by the monthly interest rate.
$375 average balance x 2% monthly interest rate = $7.50 monthly interest payment
So the monthly interest payment in this situation is $7.50
