Bryan and Adam have some stickers.
13 of Bryan's stickers is 3 less than
19 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)
19 of Adam's stickers =
13 of Bryan's stickers + 3
19 of Adam's stickers = 1 u + 3
99 of Adam's stickers = 9(1 u + 3) = 9 u + 27
(c)
Total number of stickers
= 3 u + 9 u + 27
= 12 u + 27
(d)
Difference in the number of stickers between Adam and Bryan
= 9 u + 27 - 3 u
= 9 u - 3 u + 27
= 6 u + 27
Answer(s): (a) 3 u; (b) 9 u + 27; (c) 12 u + 27; (d) 6 u + 27
