Joe collects baseball cards. He needs to make a poster of different baseball cards as a project for
art class. For this project you will need to:


Organize data
Calculate costs
ACTIVITY 1: ORGANIZE FIRST!
These are the packs that Joe bought:

Topps:
13 packs gave Joe 130 cards. The cost is $1.59 per pack.

Score:
15 packs gave Joe 150 cards. The cost is $1.79 per pack.

Donruss:
10 packs gave Joe 200 cards. The cost is $2.05 per pack.

Upper Deck: 18 packs gave Joe 144 cards. The cost is $5.50 per pack.
40. Organize this baseball card information into a table. For each baseball card company include
the following:



Cost of one baseball card pack
Number of baseball packs bought
Number of baseball cards for each baseball card company
Draw your table in the space below. You must give your table a title and label each column:

ACTIVITY 3: MAKE A PLAN
Joe needs glue to stick the baseball cards onto the poster. His poster will be 6 feet by 12 feet. Glue sticks cost $1.50
for an amount that will cover 2 square feet.
43. Explain a strategy for how many glue sticks Joe will need to complete his entire
poster.
Find out how many 2 x 2 squares will fit into the 6 x 12 area.
Or divide the total area (6 x 12) by the area of one square (2 x 2).
44. Use your strategy to find the total number of glue sticks Joe will need to complete
his entire poster. Show your work in the space below.
6 x 12 = 72
2x2=4
72  4 = 18
Total number of glue sticks needed: ____18______
45. Find the total cost for all of the glue sticks. Show your work in the space below.
$ 1.50 x 18 = 27.00
Total cost of glue sticks: $___27.00____
ACTIVITY 4: THINK BACK
46. Fred, Joe’s classmate, made a different poster that was 12 feet by 24 feet. He thinks
that for his poster he will need to use 2 times as many glue sticks as Joe’s poster.
Explain why Fred is wrong.
Fred will use 4 times as many glue sticks. This is because when you divide the area of a 6 x 12
square feet (72 sq. feet) by the area of a 12 x 24 square feet (288 sq. feet) the answer is 4, so Fred
will need 4 times as many glue sticks.
47. Explain how a change in the cost of glue sticks would affect the amount of money
Joe will spend on his poster.
If the glue sticks cost more, the project will cost more, and if glue sticks cost less, the project will cost less.
