Credit Card - unpaid balance method
Nick has a revolving department store credit card account with an annual percentage rate of 15%.
Last month’s balance on the account was $423.78.
During the current month, he made purchases totaling $123.42 and made a payment of $100.
The store uses the unpaid balance method.
According to this information, what must be the amount of the finance charge? Round your answer to the nearest cent.
I can’t seem to find a way to do an unpaid balance method for this question and finance charge. HELP ME PLEASE!
