Roshel has 4 stickers fewer than Joelle but 22 stickers more than Carl. The three children have 210 stickers altogether.
- How many stickers does Carl have?
- How many stickers does Joelle have?
(a)
Number of stickers Joelle has = 1 u
Number of stickers Roshel has = 1 u - 4
Number of stickers Carl has = 1 u - 4 - 22 = 1 u - 26
Total number of stickers
= 1 u + 1 u - 4 + 1 u - 26
= 3 u - 30
3 u - 30 = 210
3 u = 210 + 30
3 u = 240
1 u = 240 ÷ 3 = 80
Number of stickers that Carl has
= 1 u - 26
= 80 - 26
= 54
(b)
Number of stickers that Joelle has
= 1 u
= 80
Answer(s): (a) 54; (b) 80
