12 of Adam's stickers is 2 more than
17 of Bryan'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 Bryan and Adam = _____
(a)
17 of Bryan's stickers = 1 u
77 of Bryan's stickers = 7 u
Number of stickers that Bryan has = 7 u
(b)
12 of Adam's stickers =
17 of Bryan's stickers + 2
12 of Adam's stickers = 1 u + 2
22 of Adam's stickers = 2(1 u + 2) = 2 u + 4
Number of stickers that Adam has = 2 u + 4
(c)
Total number of stickers
= 7 u + 2 u + 4
= 9 u + 4
(d)
Difference in the number of stickers between Adam and Bryan
= 7 u - (2 u + 4)
= 5 u - 2 u - 4
= 5 u - 4
Answer(s): (a) 7 u; (b) 2 u + 4; (c) 9 u + 4; (d) 5 u - 4
