Lillian is making chocolate cupcakes to sell at a fundraiser. She only has 3 cups of sugar at home. She goes to the store and buys 2 bags of sugar. Each bag of sugar contains 6 cups. The batter uses 1 cup of sugar per 12 cupcakes. She needs 2 cups of sugar to make enough frosting for a dozen cupcakes. How many dozen cupcakes can she bake and ice with the sugar she has?
The bags of sugar which she bought contain 2 * 6 = <T>multiply(2, 6)=12 cups.
In total, she has 12 cups + 3 cups = <T>add(12, 3)=15 cups of sugar to use.
She needs 1 cup + 2 cups = <T>add(1, 2)=3 cups of sugar to make the batter and frosting for a dozen cupcakes.
Lillian has enough sugar to bake and ice 15 / 3 = <T>divide(15, 3)=5.0 dozen cupcakes.
