(a)
Let the number of stickers that Adam has be 1 u.
Bryan has 80 stickers less than Adam.
Bryan has 20 stickers less than Charlie.
Number of stickers that Bryan has = 1 u - 80
(b)
Charlie has 20 stickers more than Bryan.
Number of stickers that Charlie has
= 1 u - 80 + 20
= 1 u - 60
(c)
Total number of stickers
= 1 u - 80 + 1 u - 60 + 1 u
= 1 u + 1 u + 1 u - 80 - 60
= 3 u - 140
