(a)
Adam has 40 stickers more than Bryan.
Charlie has 60 stickers less than Adam.
Let the number of stickers that Bryan has be 1 u.
Adam has 40 stickers more than Bryan.
Number of stickers that Adam has = 1 u + 40
(b)
Charlie has 60 stickers less than Adam.
Number of stickers that Charlie has
= 1 u + 40 - 60
= 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 + 20
