Griffin ordered a pair of sneakers online. He had a $20 credit that he applied toward the purchase, and then he used a credit card to pay for the rest of the cost. If the shoes cost $64, how much did Griffin charge to his credit card when he bought the sneakers?
$44 64-20=44. He charged $44 dollars
$20 - $64 = $44. He charged $44 to his credit card.
