Lizzy: Bill is trying to decide whether to make blueberry muffins or raspberry muffins. Blueberries cost $5.00 per 6 ounce carton and raspberries cost $3.00 per 8 ounce carton. If Bill is going to make 4 batches of muffins, and each batch takes 12 ounces of fruit, how much money would he save by using raspberries instead of blueberries?.
Me: Hmmm, let me think. I think this is the detailed solution:
First find how many ounces of fruit Bill will need total: 12 ounces / batch * 4 batches = 48 ounces. Then find how many cartons of blueberries Bill would need: 48 ounces / 6 ounces / carton = 8 cartons. Then multiply that number by the cost per carton to find the total cost of the blueberries: 8 cartons * $5 / carton = $40. Then find how many cartons of raspberries Bill would need: 48 ounces / 8 ounces / carton = 6 cartons. Then multiply that number by the cost per carton to find the total cost of the raspberries: 6 cartons * $3 / carton = $18. Then subtract the cost of the raspberries from the cost of the blueberries to find the difference: $40 - $18 = $22. Final answer: 22.
