(a)
Bryan has 50 stickers more than Adam.
Charlie has 70 stickers less than Bryan.
Let the number of stickers that Adam has be 1 u.
Bryan has 50 stickers more than Adam.
Number of stickers that Bryan has = 1 u + 50
(b)
Charlie has 70 stickers less than Bryan.
Number of stickers that Charlie has
= 1 u + 50 - 70
= 1 u - 20
(c)
Total number of stickers
= 1 u + 50 + 1 u - 20 + 1 u
= 1 u + 1 u + 1 u + 50 - 20
= 3 u + 30
