Adam and Bryan have some stickers.
18 of Adam's stickers is 8 less than
19 of Bryan'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 Bryan and Adam = _____
(a)
18 of Adam's stickers = 1 u
88 of Adam's stickers = 8 u
(b)
19 of Bryan's stickers =
18 of Adam's stickers + 8
19 of Bryan's stickers = 1 u + 8
99 of Bryan's stickers = 9(1 u + 8) = 9 u + 72
(c)
Total number of stickers
= 8 u + 9 u + 72
= 17 u + 72
(d)
Difference in the number of stickers between Bryan and Adam
= 9 u + 72 - 8 u
= 9 u - 8 u + 72
= 1 u + 72
Answer(s): (a) 8 u; (b) 9 u + 72; (c) 17 u + 72; (d) 1 u + 72
