If 3 boys each make 12 muffins for a bake sale, and 2 other girls are making 20 muffins each, how many total muffins will be for sale? Let's think first. Chain of thought:
The boys baked a total of 3 x 12 = 36 muffins. The girls baked a total of 2 x 20 = 40 muffins. Hence, there are a total of 36 + 40 = 76 muffins that will be for sale.
Therefore, the answer is 76.
