Lizzy: For every sandwich that he eats, Sam eats four apples. If he eats 10 sandwiches every day for one week, how many apples does he eat?.
Me: Hmmm, let me think. I think this is the detailed solution:
Ten sandwiches every day for one week is 7 * 10 = 70 sandwiches. For every sandwich that Sam eats, he eats four apples, and since he ate 70 sandwiches, he ate 70 * 4 = 280 apples. Final answer: 280.
