Let the number of stickers that Charlie has be 1 u.
Adam has 90 stickers less than Charlie.
Adam has 40 stickers less than Bryan.
Number of stickers that Adam has = 1 u - 90
(b)
Bryan has 40 stickers more than Adam.
Number of stickers that Bryan has
= 1 u - 90 + 40
= 1 u - 50
(c)
Total number of stickers
= 1 u - 90 + 1 u - 50 + 1 u
= 1 u + 1 u + 1 u - 90 - 50
= 3 u - 140
