A recipe calls for 3.5 cups of flour to make 28 cookies. Maria wants to make 60 cookies using the same recipe. How many cups of flour will she need, and how does this compare to using two complete recipe batches?
- She needs 7.5 cups, which is 0.5 cups more than two complete batches would require (correct answer)
- She needs 7.5 cups, which is 0.5 cups less than two complete batches would require
- She needs 8.0 cups, which is 1.0 cup more than two complete batches would require
- She needs 8.0 cups, which is 1.0 cup less than two complete batches would require
Explanation: Unit rate: 3.5 cups ÷ 28 cookies = 0.125 cups per cookie. For 60 cookies: 60 × 0.125 = 7.5 cups. Two complete recipe batches: 2 × 3.5 = 7 cups (making 56 cookies). So 7.5 cups is 0.5 cups more than two batches would require.
