George had a previous balance on his credit card of $330.19 on which he paid $50.00. He
was assessed a finance charge of $4.20. What is his new balance?

Respuesta :

Since it’s a credit card you must subtract 330.19-50.00 = 280.19 then with the fine you add 280.19+4.20= 284.39. So the new balance is $284.39
