(a)
Adam has 20 stickers less than Charlie.
Adam has 10 stickers more than Bryan.
Let the number of stickers that Charlie has be 1 u.
Adam has 20 stickers less than Charlie.
Number of stickers that Adam has = 1 u - 20
(b)
Bryan has 10 stickers less than Adam.
Number of stickers that Bryan has
= 1 u - 20 - 10
= 1 u - 30

Total number of stickers
= 1 u - 20 + 1 u - 30 + 1 u
= 1 u + 1 u + 1 u - 20 - 30
= 3 u - 50
