Armando has a previous balance of $1,537 on a credit card with a 23.4% APR compounded monthly. If he made a payment of $84 this month, what is the new balance on his credit card?

Respuesta :

When you don't pay off your credit card then you pay the previous months interest - ouch! The interest is Prt

Current balance = Previous balance + Interest - payment
Current balance = 1537 + (1537)(23.4/100)(1/12) - (84)
Current balance = $1482.97
