Last month, Kaitlin's average daily balance on her credit card was $1,180.81. The annual interest rate on that credit card is 17.52%. The minimum payment on that card is the interest charge ( I equals B with bar on top times r over 365 times n) plus 2% of the ending balance or $25, which ever is larger. There were 31 days in that month and the ending balance was $1,903.31. Construct a balance function for the balance Kaitlin will owe after each month's payment.

B(t) = ? *(?)t
