(a)
Let the number of stickers that Charlie has be 1 u.
Adam has 70 stickers less than Charlie.
Adam has 100 stickers less than Bryan.
Number of stickers that Adam has = 1 u - 70
(b)
Bryan has 100 stickers more than Adam.
Number of stickers that Bryan has
= 1 u - 70 + 100
= 1 u + 30
(c)
Total number of stickers
= 1 u - 70 + 1 u + 30 + 1 u
= 1 u + 1 u + 1 u - 70 + 30
= 3 u - 40
Answer(s): (a) 70; (b) 30; (c) 40
