You owe $1,534.09 on a credit card that has an interest rate of 15.7% APR. You decide to put $250.00 into a savings account earning a 3.5% APR and another $500.00 toward the credit card at the beginning of the month. What is the difference in interest saved at the end of a full month between this decision and if you had paid the entire $750.00 toward the credit card?
