Bryan and Adam have some stickers.
17 of Bryan's stickers is 3 less than
18 of Adam's stickers.
Let
17 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)
17 of Bryan's stickers = 1 u
77 of Bryan's stickers = 7 u
(b)
18 of Adam's stickers =
17 of Bryan's stickers + 3
18 of Adam's stickers = 1 u + 3
88 of Adam's stickers = 8(1 u + 3) = 8 u + 24
(c)
Total number of stickers
= 7 u + 8 u + 24
= 15 u + 24
(d)
Difference in the number of stickers between Adam and Bryan
= 8 u + 24 - 7 u
= 8 u - 7 u + 24
= 1 u + 24
Answer(s): (a) 7 u; (b) 8 u + 24; (c) 15 u + 24; (d) 1 u + 24
