(a)
Bryan has 70 stickers less than Adam.
Charlie has 100 stickers more than Bryan.
Let the number of stickers that Adam has be 1 u.
Bryan has 70 stickers less than Adam.
Number of stickers that Bryan has = 1 u - 70
(b)
Charlie has 100 stickers more than Bryan.
Number of stickers that Charlie has
= 1 u - 70 + 100
= 1 u + 30
(c)
Total number of stickers
= 1 u - 70 + 1 u + 30 + 1 u
= 1 u + 1 u + 1 u - 70 + 30
= 3 u - 40
