Help me plan a birthday party for our class of 21
students. A birthday cake that costs $9.00 can serve 8 people and a
larger cake that costs $13 can serve 12 people. Which size cakes should
I buy for our party to get the best deal? Why?
For 4th and 5th graders: Suppose there is also a cake that will serve 6 people for $8.00 and another class of 21 students join our party. Which size cakes should I buy now to get the best deal? Why?
