Uh oh — Alex neglected to make his payment on time. As a result, the bank charged him a $20 late fee. Therefore the total amount Alex ended up paying the bank was $238.00. Had he paid cash, the game console would have cost him $211.94. How much did using a credit card cost him?
(Watch out! The bank includes the late fee in the outstanding balance, which means Alex will have to pay interest on that amount too! Ouch!!)
