(a)
Bryan has 20 stickers more than Adam.
Bryan has 90 stickers less than Charlie.
Let the number of stickers that Adam has be 1 u.
Number of stickers that Bryan has = 1 u + 20
(b)
Number of stickers that Charlie has
= 1 u + 20 + 90
= 1 u + 110
(c)
Total number of stickers
= 1 u + 20 + 1 u + 1 u + 110
= 1 u + 1 u + 1 u + 20 + 110
= 3 u + 130
