Adam and Bryan have some stickers.
17 of Adam's stickers is 2 less than
111 of Bryan's stickers.
Let
17 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)
17 of Adam's stickers = 1 u
77 of Adam's stickers = 7 u
(b)
111 of Bryan's stickers =
17 of Adam's stickers + 2
111 of Bryan's stickers = 1 u + 2
1111 of Bryan's stickers = 11(1 u + 2) = 11 u + 22
(c)
Total number of stickers
= 7 u + 11 u + 22
= 18 u + 22
(d)
Difference in the number of stickers between Bryan and Adam
= 11 u + 22 - 7 u
= 11 u - 7 u + 22
= 4 u + 22
Answer(s): (a) 7 u; (b) 11 u + 22; (c) 18 u + 22; (d) 4 u + 22
