(a)
Charlie has 60 stickers more than Adam.
Bryan has 100 stickers less than Charlie.
Let the number of stickers that Adam has be 1 u.
Charlie has 60 stickers more than Adam.
Number of stickers that Charlie has = 1 u + 60
(b)
Bryan has 100 stickers less than Charlie.
Number of stickers that Bryan has
= 1 u + 60 - 100
= 1 u - 40
(c)
Total number of stickers
= 1 u + 60 + 1 u - 40 + 1 u
= 1 u + 1 u + 1 u + 60 - 40
= 3 u + 20
