Answer:
you can save $522.48 by purchasing the computer with the credit card
Step-by-step explanation:
total money paid to the credit card company = $181.46 x 12 = $2,177.52
total money paid for renting the computer = $200 x 12 = $2,400, plus the final payment = $2,400 + $300 = $2,700
money saved by using the credit card = $2,700 - $2,177.52 = $522.48
