the opening balance of one of the 31-day billing cycles for suzy's credit card was $7400, but after 15 days suzy made a payment of $4900 to decrease her balance, and it stayed the same for the remainder of the billing cycle. if her credit card's apr is 22%, how much more in interest would she pay for the billing cycle with the previous balance method than with the adjusted balance method?
Given:
31 days = 7,400
15 days = payment of 4,900
16 days = 7,400 - 4,900 = 2,500
Method 1:
7,400 22% 31/365 = 138.27
Method 2: adjusted balance
7,400 22% 15/365 = 66.90
2,500 22% 16/365 = 24.11
66.90 + 24.11 = 90.21
138.27 - 90.21 = 48.06
She would pay 48.06 more with the previous balance method than with the adjusted balance method.
