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

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