(a)
Adam has 30 stickers less than Bryan.
Adam has 40 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 40 stickers less than Adam.
Number of stickers that Charlie has
= 1 u - 30 - 40
= 1 u - 70
(c)
Total number of stickers
= 1 u - 30 + 1 u - 70 + 1 u
= 1 u + 1 u + 1 u - 30 - 70
= 3 u - 100
