Adam has
56 as many as Bryan.
Charlie has 70 less stickers than Adam.
Let the number of stickers that Bryan has be 6 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 = 6 u
Number of stickers that Adam has = 5 u
(b)
Number of stickers that Charlie has = 5 u - 70
(c)
Total number of stickers
= 6 u + 5 u + 5 u - 70
= 16 u - 70
(d)
Number of stickers that Bryan has more than Charlie
= 6 u - (5 u - 70)
= 6 u - 5 u + 70
= 1 u + 70
Answer(s): (a) 5 u; (b) 5 u - 70; (c) 16 u - 70; (d) 1 u + 70
