On Kathleen's credit card statement, her last balance was $89.70. She made a payment of $20, had new charges totalling $32.11, and pays a periodic rate of 1.23 percent. What is her unpaid balance?

102.91
77.59
101.81
69.70

Respuesta :

Well, the first $100 gets charged $1.50 

The next 146.07 gets charged 1% so that is 1.46 

1.50 + 1.46 = 2.96 

2.3 89.70 - 20 + 32.11 = 101.81. 1.23 percent of that is 1.25

The answer would be the third choice.
