(a)
Charlie has 100 stickers more than Bryan.
Adam has 20 stickers less than Charlie.
Let the number of stickers that Bryan has be 1 u.
Charlie has 100 stickers more than Bryan.
Number of stickers that Charlie has = 1 u + 100
(b)
Adam has 20 stickers less than Charlie.
Number of stickers that Adam has
= 1 u + 100 - 20
= 1 u + 80
(c)
Total number of stickers
= 1 u + 100 + 1 u + 80 + 1 u
= 1 u + 1 u + 1 u + 100 + 80
= 3 u + 180
