Bryan and Adam have some stickers.
16 of Bryan's stickers is 9 less than
18 of Adam's stickers.
Let
16 of Bryan's stickers be 1 u.
- Number of stickers that Bryan has = _____
- Number of stickers that Adam has = _____
- Total number of stickers = _____
- Difference in the number of stickers between Adam and Bryan = _____
(a)
16 of Bryan's stickers = 1 u
66 of Bryan's stickers = 6 u
(b)
18 of Adam's stickers =
16 of Bryan's stickers + 9
18 of Adam's stickers = 1 u + 9
88 of Adam's stickers = 8(1 u + 9) = 8 u + 72
(c)
Total number of stickers
= 6 u + 8 u + 72
= 14 u + 72
(d)
Difference in the number of stickers between Adam and Bryan
= 8 u + 72 - 6 u
= 8 u - 6 u + 72
= 2 u + 72
Answer(s): (a) 6 u; (b) 8 u + 72; (c) 14 u + 72; (d) 2 u + 72
