Michael saved 5 of his cookies to give Sarah, who saved a third of her 9 cupcakes to give to Michael. How many desserts does Sarah end up with? Let's answer step by step:
Sarah saved 1 / 3 of her 9 cupcakes to give Michael, so she has 2 / 3 x 9 = 6 cupcakes left. Michael saves 5 of his cookies for Sarah, which she adds to her 6 cupcakes. Sarah has 5 + 6 = 11 desserts. The answer: 11.
