(a)
Let the number of stickers that Charlie has be 1 u.
Adam has 80 stickers less than Charlie.
Adam has 30 stickers less than Bryan.
Number of stickers that Adam has = 1 u - 80
(b)
Bryan has 30 stickers more than Adam.
Number of stickers that Bryan has
= 1 u - 80 + 30
= 1 u - 50
(c)
Total number of stickers
= 1 u - 80 + 1 u - 50 + 1 u
= 1 u + 1 u + 1 u - 80 - 50
= 3 u - 130
Answer(s): (a) 80; (b) 50; (c) 130
