Adam has
35 as many as Bryan.
Charlie has 40 less stickers than Adam.
Let the number of stickers that Bryan has be 5 u.
- Number of stickers that Adam has = _____
- Number of stickers that Charlie has = _____
- Total number of stickers = _____
- Number of stickers that Bryan has more than Charlie = _____
(a)
Let the number of stickers that Bryan has = 5 u
Number of stickers that Adam has = 3 u
(b)
Number of stickers that Charlie has = 3 u - 40
(c)
Total number of stickers
= 5 u + 3 u + 3 u - 40
= 11 u - 40
(d)
Number of stickers that Bryan has more than Charlie
= 5 u - (3 u - 40)
= 5 u - 3 u + 40
= 2 u + 40
Answer(s): (a) 3 u; (b) 3 u - 40; (c) 11 u - 40; (d) 2 u + 40
