The graph shows the number of pens 3 students collected. Study the graph and answer the following.
- Who collected 20 pens? Give the answer in number. (Eg 1)
- Which 2 students collected a total of 52 pens? Give the answer in numbers. (Eg 1, 2)
- How many pens must Mary give to Zoe so that both of them would have the same number of pens?
(a)
4 pens → 1 box
20 pens → 20 ÷ 4 = 5 boxes
(3) Zoe has 5 boxes so she collected 20 pens.
(b)
Total number of boxes represented by 52 pens
= 52 ÷ 4
= 13
Number of boxes that Kay and Zoe had
= 8 + 5
= 13
2 students who collected a total of 52 pens are (1) Kay and (3) Zoe.
(c)
Difference in the number of boxes between Mary and Zoe
= 6 - 5
= 1
Number of pens that Mary must give to Zoe
= 1 ÷ 2 x 4
= 2
Answer(s): (a) 3; (b) 1, 3; (c) 2
