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.
 
        
             
        
        
        
Answer:

The function f(x) - g(x) is an illustration of a composite function
Leanne's end result of f(x) - g(x) = -1/2x + 9 is correct
<h3>How to estimate the student's answer?</h3>
The functions are given as:
f(x) = 1/2x + 6
g(x) = x - 3
The function f(x) - g(x) is calculated using:
f(x) - g(x) = 1/2x + 6 - x + 3
Collect like terms
f(x) - g(x) = 1/2x - x + 6  + 3
Evaluate the like terms
f(x) - g(x) = -1/2x + 9
By comparing the above solution to the students' response, we can see that:
Leanne's end result of f(x) - g(x) = -1/2x + 9 is correct
