Lizzy: Chad sandwiches 2 crackers with a scoop of peanut butter. He has 5 of these crackers a night before bed. A box of crackers has 4 sleeves with each sleeve holding 28 crackers. How many nights will 5 boxes of crackers last him?.
Me: Hmmm, let me think. I think this is the detailed solution:
Chad uses 2 crackers for each "sandwich" and has 5 sandwiches a night so he eats 2 * 5 = 10 crackers a night. The box has 4 sleeves of crackers and each sleeve has 28 crackers for a total of 4 * 28 = 112 crackers. 1 box has 112 crackers so 5 boxes will have 112 * 5 = 560 crackers. He eats 10 crackers a night and 5 boxes have 560 crackers so they will last him 560 / / 10 = 56 nights. Final answer: 56.
