(a)
Charlie has 50 stickers more than Bryan.
Adam has 80 stickers less than Charlie.
Let the number of stickers that Bryan has be 1 u.
Charlie has 50 stickers more than Bryan.
Number of stickers that Charlie has = 1 u + 50
(b)
Adam has 80 stickers less than Charlie.
Number of stickers that Adam has
= 1 u + 50 - 80
= 1 u - 30

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