Solution

Problem 14 :

A science museum makes gift bags for students using 168 magnets, 48 robot figurines, and 24 packs of freeze-dried ice cream.

What is the greatest number of gift bags that can be made using all of the items?

How many of each item are in each gift bag?

Solution

Answer Key

a)  6ab² = 2 ∙ 3  ∙ a  ∙ b ∙ b

b)  52w = 2 ∙ 2 ∙ 13 ∙ w

c)  2r³s = 2 ∙ r ∙ r ∙ r ∙ s

d)  7xyz = 7 ∙ x ∙ y ∙ z

1)  

Coefficient : 11

Variables : c, d

Degree : 2

5)

Coefficient : 5

Variables : x, y

Degree : 3

2)

Coefficient : 19

Variable : m

Degree : 3

6)

Coefficient : 35

Variables : r, s

Degree : 6

3)  

Constant : 3

Variable : f 

degree : 6

7)

Coefficient : 2

Variables : y, z

Degree : 7

4)

Coefficient : 21

Variables : a, b

Degree : 2 

8)

Coefficient : 40

Variables : m, n

Degree : 3

3)  GCF = 2m²n

4)  GCF = 2a

5)  GCF = 4mn

6)  GCF = ab³

7)  GCF = x

8)  GCF = s

9)  GCF = 9wx

10)  GCF = y

11) GCF = s

12)  a)  Greatest common factor = 7

b)  Greatest common factor = 6

c)  Greatest common factor = 14.

13)  Greatest common factor of 16 and 24 is 8. So, in each arrangement we should use 8 balloons.

14)  So, the greatest number of gift bags = 24. This means the maximum number of identical gift bags that can be made is 24. 

  • Magnets: 168 magnets / 24 bags = 7 magnets per bag
  • Robot figurines: 48 figurines / 24 bags = 2 figurines per bag
  • Freeze-dried ice cream: 24 packs / 24 bags = 1 pack per bag
