Bryan and Adam have some stickers.
13 of Bryan's stickers is 7 less than
14 of Adam's stickers.
Let
13 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)
13 of Bryan's stickers = 1 u
33 of Bryan's stickers = 3 u
(b)
14 of Adam's stickers =
13 of Bryan's stickers + 7
14 of Adam's stickers = 1 u + 7
44 of Adam's stickers = 4(1 u + 7) = 4 u + 28
(c)
Total number of stickers
= 3 u + 4 u + 28
= 7 u + 28
(d)
Difference in the number of stickers between Adam and Bryan
= 4 u + 28 - 3 u
= 4 u - 3 u + 28
= 1 u + 28
Answer(s): (a) 3 u; (b) 4 u + 28; (c) 7 u + 28; (d) 1 u + 28
