Kate made a birthday cake for Bryan’s second birthday. Can you guess who his favorite Sesame Street character is? Needless to say, the cake was a HUGE success! So one of the guests on the party (who is a preschool director) thought how awesome it would be to have a cake like this for the Open House next week! She asked Kate to make one for her. She wanted to have a cake in which Elmos’s nose was 6 inches in diameter, because the preschool is 6 years old. On Kate’s cake Elmo’s nose is 2 inches. Also, the new cake will be proportionally taller as well. Kate has to get busy! The first thing she needs to do is to figure out how much of each ingredient she will need.

Her original recipe of the cake batter called for:

1. 3 eggs

2. baking mix

3. Half a cup of oil

4. 1 cup of water

a. How much of each ingredient will she need? Explain how you know it.

b. If Kate spent $3.50 on the ingredients of the cake, how much money should the

director give her for the ingredients?

Kate used altogether 2 cups of frosting: 1 cup of red, a half a cup of black, and a quarter cup of each white and orange.

c. How much of each frosting will she need for the big cake? Explain how you know it. (Keep in mind that the bigger cake doesn’t have proportionally thicker frosting…)

d. If the original cake contained 24 servings, how many servings will there be in the big cake? Explain how you know.

e. Kate’s first cake is on a 10-inch platter. How big of a platter will the director need for her cake? Explain how you know it. For the ingredients? Kate used altogether 2 cups of frosting: 1 cup of red, a half a cup of black, and a quarter cup of each white and orange.
