(a)
Adam has 50 stickers less than Charlie.
Bryan has 70 stickers more than Adam.
Let the number of stickers that Charlie has be 1 u.
Adam has 50 stickers less than Charlie.
Number of stickers that Adam has = 1 u - 50
(b)
Bryan has 70 stickers more than Adam.
Number of stickers that Bryan has
= 1 u - 50 + 70
= 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 - 30
Answer(s): (a) 50; (b) 20; (c) 30
