Adam has 80 less stickers than Charlie.
Let the number of stickers that Bryan has be 9 u.
- Number of stickers that Charlie has = _____
- Number of stickers that Adam has = _____
- Total number of stickers = _____
- Number of stickers that Bryan has more than Adam = _____
(a)
Let the number of stickers that Bryan has = 9 u
Number of stickers that Charlie has = 5 u
(b)
Number of stickers that Adam has = 5 u - 80
(c)
Total number of stickers
= 9 u + 5 u + 5 u - 80
= 19 u - 80

Number of stickers that Bryan has more than Adam
= 9 u - (5 u - 80)
= 9 u - 5 u + 80
= 4 u + 80
Answer(s): (a) 5 u; (b) 5 u - 80; (c) 19 u - 80; (d) 4 u + 80
