Adam has
34 as many as Bryan.
Charlie has 20 less stickers than Adam.
Let the number of stickers that Bryan has be 4 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 = 4 u
Number of stickers that Adam has = 3 u
(b)
Number of stickers that Charlie has = 3 u - 20
(c)
Total number of stickers
= 4 u + 3 u + 3 u - 20
= 10 u - 20
(d)
Number of stickers that Bryan has more than Charlie
= 4 u - (3 u - 20)
= 4 u - 3 u + 20
= 1 u + 20
Answer(s): (a) 3 u; (b) 3 u - 20; (c) 10 u - 20; (d) 1 u + 20
