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?
The boys baked a total of 3 x 12 = <T>multiply(3, 12)=36 muffins.
The girls baked a total of 2 x 20 = <T>multiply(2, 20)=40 muffins.
Hence, there are a total of 36 + 40 = <T>add(36, 40)=76 muffins that will be for sale.
