Charlie has
58 as many as Adam.
Bryan has 90 less stickers than Charlie.
Let the number of stickers that Adam has be 8 u.
- Number of stickers that Charlie has = _____
- Number of stickers that Bryan has = _____
- Total number of stickers = _____
- Number of stickers that Adam has more than Bryan = _____
(a)
Let the number of stickers that Adam has = 8 u
Number of stickers that Charlie has = 5 u
(b)
Number of stickers that Bryan has = 5 u - 90
(c)
Total number of stickers
= 8 u + 5 u + 5 u - 90
= 18 u - 90
(d)
Number of stickers that Adam has more than Bryan
= 8 u - (5 u - 90)
= 8 u - 5 u + 90
= 3 u + 90
Answer(s): (a) 5 u; (b) 5 u - 90; (c) 18 u - 90; (d) 3 u + 90
