Adam and Bryan have some stickers.
12 of Adam's stickers is 11 less than
17 of Bryan's stickers.
Let
12 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)
12 of Adam's stickers = 1 u
22 of Adam's stickers = 2 u
(b)
17 of Bryan's stickers =
12 of Adam's stickers + 11
17 of Bryan's stickers = 1 u + 11
77 of Bryan's stickers = 7(1 u + 11) = 7 u + 77
(c)
Total number of stickers
= 2 u + 7 u + 77
= 9 u + 77
(d)
Difference in the number of stickers between Bryan and Adam
= 7 u + 77 - 2 u
= 7 u - 2 u + 77
= 5 u + 77
Answer(s): (a) 2 u; (b) 7 u + 77; (c) 9 u + 77; (d) 5 u + 77
