Fredricka wants to buy the new Lift-o-matic gym for arm wrestling champions. It costs $1253. She could put it on her credit card that has a monthly interest rate of 18.9% (lower than many real credit card interest rates). If she takes 3 years to pay it off, how much did she pay total for the Lift-o-matic gym? How much of what Fredrick paid was just interest? or how much money could she save by earning up the money and not putting this on her credit card?
