Answer 1

Answer:

• 24y - 0.85x

Explanation:

The finance charge is the difference between the amount paid for the purchase with financing and the amount you would pay if you do not finance the purchase, that is, if you buy it in cash.

The amount paid with financing is the down payment plus all the montly payments. This is:

• down payment + number of monly payments × montly payment

• 15% of x dollars + 24 × y dollars = 0.15x + 24y

The amount that you would pay without financing is the price of the refrigerator:

• x

The difference is:

• 0.15x + 24y - x = 24y - 0.85x
