Adam and Bryan have some stickers.
13 of Adam's stickers is 11 less than
112 of Bryan's stickers.
Let
13 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)
13 of Adam's stickers = 1 u
33 of Adam's stickers = 3 u
(b)
112 of Bryan's stickers =
13 of Adam's stickers + 11
112 of Bryan's stickers = 1 u + 11
1212 of Bryan's stickers = 12(1 u + 11) = 12 u + 132
(c)
Total number of stickers
= 3 u + 12 u + 132
= 15 u + 132
(d)
Difference in the number of stickers between Bryan and Adam
= 12 u + 132 - 3 u
= 12 u - 3 u + 132
= 9 u + 132
Answer(s): (a) 3 u; (b) 12 u + 132; (c) 15 u + 132; (d) 9 u + 132
