(a)
Adam has 30 stickers more than Charlie.
Adam has 90 stickers less than Bryan.
Let the number of stickers that Charlie has be 1 u.
Number of stickers that Adam has = 1 u + 30
(b)
Number of stickers that Bryan has
= 1 u + 30 + 90
= 1 u + 120

Total number of stickers
= 1 u + 30 + 1 u + 1 u + 120
= 1 u + 1 u + 1 u + 30 + 120
= 3 u + 150
