Show and explain your work. Draw pictures or make tables to explain your answer.

You are planning a class party. You must spend between $2.00 and $2.50 per person on food. There are 18 students in your class. The class has decided that each person will be served 2 slices of pizza. You must use all items from the table.


Item
Price
Servings
Pizza
$9.00
12 servings
Cookies
$2.50/box
12 servings
Juice
$2.50/ half gallon

Use the above table to calculate how many of each item you will buy and what the cost will be. Explain why you bought the quantities of each item that you did.



































Answers for Sheet # 28

Amount of money you have = 18 x $2 = 36 (minimum)

Maximum money you have = 18 x $2.50 = $45

Pizza
Cookies
Juice
Total
3 x $9 = 27
2 x $2.50 = $5.00
2 x $2.50 = $5.00
$37.00
3 x $9 = 27
2 x $2.50 = $5.00
3 x $2.50 = $7.50
$39.50

You can make other combinations so long you stay between $36 and $45 and still serve all students.
