(a)
Total number of stickers received = 4 u
4 u = 80
1 u = 80 ÷ 4 = 20
Total number of stickers that Carl, Elijah and Justin received
= 80 - 20
= 60
Total number of stickers that Carl, Elijah and Justin received
= 1 p + 4 p
= 5 p
1 p = 60 ÷ 5 = 12
Number of stickers that Carl received
= 1 p
= 12
(b)
Number of more stickers that Oliver received more than Elijah
= 1 u - 1 p
= 20 - 12
= 8
Answer(s): (a) 12; (b) 8
