Question

Xavier buys a computer for $525, which includes taxes. He pays for the computer over a 12-month period by paying $48.13 per month. Which statement about Xavier’s purchase is most likely true?
He used a debit card to make the purchase and paid exactly $525 for the computer.
He used a debit card to make the purchase and paid an additional $52.56 in interest.
He used a credit card to make the purchase and paid exactly $525 for the computer.
He used a credit card to make the purchase and paid an additional $52.56 in interest.

Answer 1

Total paid = 48.13 × 12 = 577.56.
Extra paid = 577.56 − 525 = 52.56.

So he most likely used a credit card and paid an additional $52.56 in interest.
