For (a) to (d), give the answers in units (Eg 1 u) or unit equations (Eg 1 u + 2).
Adam and Bryan have some stickers.
12 of Adam's stickers is 10 less than
111 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)
111 of Bryan's stickers =
12 of Adam's stickers + 10
111 of Bryan's stickers = 1 u + 10
1111 of Bryan's stickers = 11(1 u + 10) = 11 u + 110
(c)
Total number of stickers
= 2 u + 11 u + 110
= 13 u + 110
(d)
Difference in the number of stickers between Bryan and Adam
= 11 u + 110 - 2 u
= 11 u - 2 u + 110
= 9 u + 110
Answer(s): (a) 2 u; (b) 11 u + 110; (c) 13 u + 110; (d) 9 u + 110
