(a)
Charlie has 50 stickers less than Adam.
Bryan has 90 stickers more than Charlie.
Let the number of stickers that Adam has be 1 u.
Charlie has 50 stickers less than Adam.
Number of stickers that Charlie has = 1 u - 50
(b)
Bryan has 90 stickers more than Charlie.
Number of stickers that Bryan has
= 1 u - 50 + 90
= 1 u + 40
(c)
Total number of stickers
= 1 u - 50 + 1 u + 40 + 1 u
= 1 u + 1 u + 1 u - 50 + 40
= 3 u - 10
Answer(s): (a) 50; (b) 40; (c) 10
