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