(a)
Let the number of stickers that Charlie has be 1 u.
Bryan has 100 stickers less than Charlie.
Bryan has 20 stickers less than Adam.
Number of stickers that Bryan has = 1 u - 100
(b)
Adam has 20 stickers more than Bryan.
Number of stickers that Adam has
= 1 u - 100 + 20
= 1 u - 80
(c)
Total number of stickers
= 1 u - 100 + 1 u - 80 + 1 u
= 1 u + 1 u + 1 u - 100 - 80
= 3 u - 180
Answer(s): (a) 100; (b) 80; (c) 180
