Adam and Bryan have some stickers.
14 of Adam's stickers is 9 less than
15 of Bryan's stickers.
Let
14 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)
14 of Adam's stickers = 1 u
44 of Adam's stickers = 4 u
(b)
15 of Bryan's stickers =
14 of Adam's stickers + 9
15 of Bryan's stickers = 1 u + 9
55 of Bryan's stickers = 5(1 u + 9) = 5 u + 45
(c)
Total number of stickers
= 4 u + 5 u + 45
= 9 u + 45
(d)
Difference in the number of stickers between Bryan and Adam
= 5 u + 45 - 4 u
= 5 u - 4 u + 45
= 1 u + 45
Answer(s): (a) 4 u; (b) 5 u + 45; (c) 9 u + 45; (d) 1 u + 45
