(a)
Charlie has 90 stickers more than Bryan.
Adam has 100 stickers less than Charlie.
Let the number of stickers that Bryan has be 1 u.
Charlie has 90 stickers more than Bryan.
Number of stickers that Charlie has = 1 u + 90
(b)
Adam has 100 stickers less than Charlie.
Number of stickers that Adam has
= 1 u + 90 - 100
= 1 u - 10

= 1 u + 90 + 1 u - 10 + 1 u
= 1 u + 1 u + 1 u + 90 - 10
= 3 u + 80
