(a)
Let the number of stickers that Bryan has be 1 u.
Charlie has 100 stickers less than Bryan.
Charlie has 70 stickers less than Adam.
Number of stickers that Charlie has = 1 u - 100
(b)
Adam has 70 stickers more than Charlie.
Number of stickers that Adam has
= 1 u - 100 + 70
= 1 u - 30
(c)
Total number of stickers
= 1 u - 100 + 1 u - 30 + 1 u
= 1 u + 1 u + 1 u - 100 - 30
= 3 u - 130
Answer(s): (a) 100; (b) 30; (c) 130
