Big Idea: Many important practical and mathematical applications involve comparing quantities of one kind or another; it is important to know which method to use and how we should use them.

Essential Question: What methods are there for comparing things?

A: 4pizzas/10 campers ( =40%) 3pizzas/8campers ( =38%) B: 8 large tables/ 5 small tables = seats for 120 campers

 * __Problem 3.3- Sharing Pizza__**
 * Question A: If the pizzas at a table are shared by everyone at the table, will a person sitting at a small table get the same amount of pizza as a person sitting at a large table? Explain your reasoning.**

Answer: No. A person at a small table will not receive the same amount of pizza that a person at a large table will. This is because in the large table a person will get 40% of a pizza and in a small table a person will only get 38% of a pizza.


 * Question B: The ratio of small tables to large tables is 8 to 5. There are exactly enough seats for 240 campers. How many tables of each kind are there?**

Answer: There are 16 large tables (160 seats) and 10 small tables (80 seats). (80+160=240 seats)

Follow Up A. Ratios were helpful in this problem because firstly it helps you understand the values in the problem more clearly. You can also find percents from the ratios which will help you answer question A. The ratios also help you answer question B. You can just multiply the ratio 8:5 by 2 and you will get the ratio needed for the number of tables.
 * 1Q. How were ratios helpful in thinking about this problem?**

A. The cook will need 94 pizzas. (Pizzas on large tables=64+ pizzas on small table=30, 64+30=94)
 * 2Q. How many pizzas will the cook need in order to put four on each large table and three on each small table?**
