Sally eats 2 sandwiches on Saturday and 1 sandwich on Sunday. If each sandwich uses 2 pieces of bread, how many pieces of bread does Sally eat across Saturday and Sunday? Let's think first. Chain of thought:
Across Saturday and Sunday, Sally eats 2 + 1 = 3 sandwiches. Since each sandwich sues 2 pieces of bread, Sally eats 3 * 2 = 6 pieces of bread.
Therefore, the answer is 6.
