12 of Bryan's stickers is 9 more than
18 of Adam's stickers.
Let
18 of Adam's stickers be 1 u.
- Number of stickers that Adam has = _____
- Number of stickers that Bryan has = _____
- Total number of stickers = _____
- Difference in the number of stickers between Adam and Bryan = _____
(a)
18 of Adam's stickers = 1 u
88 of Adam's stickers = 8 u
Number of stickers that Adam has = 8 u
(b)
12 of Bryan's stickers =
18 of Adam's stickers + 9
12 of Bryan's stickers = 1 u + 9
22 of Bryan's stickers = 2(1 u + 9) = 2 u + 18
Number of stickers that Bryan has = 2 u + 18
(c)
Total number of stickers
= 8 u + 2 u + 18
= 10 u + 18
(d)
Difference in the number of stickers between Bryan and Adam
= 8 u - (2 u + 18)
= 6 u - 2 u - 18
= 6 u - 18
Answer(s): (a) 8 u; (b) 2 u + 18; (c) 10 u + 18; (d) 6 u - 18
