(a)
Let the number of stickers that Adam has be 1 u.
Charlie has 40 stickers less than Adam.
Charlie has 20 stickers less than Bryan.
Number of stickers that Charlie has = 1 u - 40

Bryan has 20 stickers more than Charlie.
Number of stickers that Bryan has
= 1 u - 40 + 20
= 1 u - 20

Total number of stickers
= 1 u - 40 + 1 u - 20 + 1 u
= 1 u + 1 u + 1 u - 40 - 20
= 3 u - 60
