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