(a)
Let the number of stickers that Bryan has be 1 u.
Adam has 50 stickers less than Bryan.
Adam has 80 stickers less than Charlie.
Number of stickers that Adam has = 1 u - 50
(b)
Charlie has 80 stickers more than Adam.
Number of stickers that Charlie has
= 1 u - 50 + 80
= 1 u + 30
(c)
Total number of stickers
= 1 u - 50 + 1 u + 30 + 1 u
= 1 u + 1 u + 1 u - 50 + 30
= 3 u - 20
Answer(s): (a) 50; (b) 30; (c) 20
