Answer:
option A. Multiply the unpaid balance by the monthly interest rate
Step-by-step explanation:
Finance charges are the monthly service fee charged by lender on the credit used by borrower if they wish to skip the payment of monthly bill and carry forward it to next month.
So, we can calculate finance charges as monthly interest accrued on the unpaid balance.
Finance charges = Unpaid balance x Monthly interest rate.
Hence, option A is correct, i.e. Multiply the unpaid balance by the monthly interest rate.

The general rule for difference of two squares is that when factorised it can be written in the form (a+b)(a-b) where a is the square root of the first part of the function and b is the square root of the second part of the function.
From this we can find the square root of x² to find a and the square root of 16y² to find b.
In this case √x²=x and √16y²=4y
Therefore fully factorised it can be written as (x+4y)(x-4y)
