New purchases = $113.98

To calculate : The unpaid balance, finance charge, and new balance using the unpaid balance method.  

Solution :  

Unpaid balance = Previous balance - Payments

Finance charge = Finance rate × Unpaid balance

Finance charge =

Finance charge = $0.8544

New balance =  Unpaid balance + finance charge + new transaction

New balance =  $56.96 +$0.8544+ $113.98

New balance =$171.7944
