(a)
Adam has 30 stickers less than Bryan.
Adam has 20 stickers more than Charlie.
Let the number of stickers that Bryan has be 1 u.
Adam has 30 stickers less than Bryan.
Number of stickers that Adam has = 1 u - 30
(b)
Charlie has 20 stickers less than Adam.
Number of stickers that Charlie has
= 1 u - 30 - 20
= 1 u - 50

Total number of stickers
= 1 u - 30 + 1 u - 50 + 1 u
= 1 u + 1 u + 1 u - 30 - 50
= 3 u - 80
