(a)
Adam has 70 stickers more than Charlie.
Bryan has 90 stickers less than Adam.
Let the number of stickers that Charlie has be 1 u.
Adam has 70 stickers more than Charlie.
Number of stickers that Adam has = 1 u + 70
(b)
Bryan has 90 stickers less than Adam.
Number of stickers that Bryan has
= 1 u + 70 - 90
= 1 u - 20
(c)
Total number of stickers
= 1 u + 70 + 1 u - 20 + 1 u
= 1 u + 1 u + 1 u + 70 - 20
= 3 u + 50
