Question. Robbie is tracking his nutrition intake per week. He eats 3 cups of rice in the morning, 2 cups of rice in the afternoon, and 5 cups of rice in the evening. If a cup of rice has 10 grams of fat, how many grams of fat does Robbie get in a week?
Answer. 700
What step-by-step reasoning justifies that answer?
Reasoning: Robbie gets 3 x 10 = 30 grams of fat every morning. He gets 10 x 2 = 20 grams of fat every afternoon. And he gets 5 x 10 = 50 grams of fat every evening. So, the total grams of fat he gets every day is 50 + 30 + 20 = 100. Therefore, the total grams of fat he gets every week is 100 x 7 = 700.
