(a)
Let the number of stickers that Bryan has be 1 u.
Charlie has 70 stickers less than Bryan.
Charlie has 80 stickers less than Adam.
Number of stickers that Charlie has = 1 u - 70
(b)
Adam has 80 stickers more than Charlie.
Number of stickers that Adam has
= 1 u - 70 + 80
= 1 u + 10
(c)
Total number of stickers
= 1 u - 70 + 1 u + 10 + 1 u
= 1 u + 1 u + 1 u - 70 + 10
= 3 u - 60
