Lionel went to the grocery store and bought 14 boxes of Graham crackers and 15 packets of Oreos. To make an Oreo cheesecake, Lionel needs 2 boxes of Graham crackers and 3 packets of Oreos. After making the maximum number of Oreo cheesecakes he can with the ingredients he bought, how many boxes of Graham crackers would he have left over?
Thoughts? Step-by-step reasoning:
Lionel has enough Graham crackers to make 14 / 2 = 7 Oreo cheesecakes. Lionel has enough Oreos to make 15 / 3 = 5 Oreo cheesecakes. Therefore, the maximum number of cheesecakes Lionel can make is 5. Lionel needs 2 * 5 = 10 boxes of Graham crackers to make 4 cheesecakes. He'll have 14 - 10 = 4 boxes left over.
Thus, the answer is 4.
