Bryan has 90 stickers more than Charlie.
Bryan has 30 stickers less than Adam.
Let the number of stickers that Charlie has be 1 u.
Number of stickers that Bryan has = 1 u + 90
(b)
Number of stickers that Adam has
= 1 u + 90 + 30
= 1 u + 120
(c)
Total number of stickers
= 1 u + 90 + 1 u + 1 u + 120
= 1 u + 1 u + 1 u + 90 + 120
= 3 u + 210
