(a)
Charlie has 40 stickers less than Adam.
Charlie has 20 stickers more than Bryan.
Let the number of stickers that Adam has be 1 u.
Charlie has 40 stickers less than Adam.
Number of stickers that Charlie has = 1 u - 40
(b)
Bryan has 20 stickers less than Charlie.
Number of stickers that Bryan has
= 1 u - 40 - 20
= 1 u - 60
(c)
Total number of stickers
= 1 u - 40 + 1 u - 60 + 1 u
= 1 u + 1 u + 1 u - 40 - 60
= 3 u - 100
Answer(s): (a) 40; (b) 60; (c) 100
