Let the number of stickers that Bryan has be 1 u.
Adam has 30 stickers less than Bryan.
Adam has 10 stickers less than Charlie.
Number of stickers that Adam has = 1 u - 30

Charlie has 10 stickers more than Adam.
Number of stickers that Charlie has
= 1 u - 30 + 10
= 1 u - 20

Total number of stickers
= 1 u - 30 + 1 u - 20 + 1 u
= 1 u + 1 u + 1 u - 30 - 20
= 3 u - 50
