(a)
Let the number of stickers that Adam has be 1 u.
Bryan has 60 stickers less than Adam.
Bryan has 90 stickers less than Charlie.
Number of stickers that Bryan has = 1 u - 60
(b)
Charlie has 90 stickers more than Bryan.
Number of stickers that Charlie has
= 1 u - 60 + 90
= 1 u + 30
(c)
Total number of stickers
= 1 u - 60 + 1 u + 30 + 1 u
= 1 u + 1 u + 1 u - 60 + 30
= 3 u - 30
