For (a) to (d), give the answers in units (Eg 1 u) or unit equations (Eg 1 u + 2).
Bryan and Adam have some stickers.
111 of Bryan's stickers is 10 less than
112 of Adam's stickers.
Let
111 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 Adam and Bryan = _____
(a)
111 of Bryan's stickers = 1 u
1111 of Bryan's stickers = 11 u
(b)
112 of Adam's stickers =
111 of Bryan's stickers + 10
112 of Adam's stickers = 1 u + 10
1212 of Adam's stickers = 12(1 u + 10) = 12 u + 120
(c)
Total number of stickers
= 11 u + 12 u + 120
= 23 u + 120
(d)
Difference in the number of stickers between Adam and Bryan
= 12 u + 120 - 11 u
= 12 u - 11 u + 120
= 1 u + 120
Answer(s): (a) 11 u; (b) 12 u + 120; (c) 23 u + 120; (d) 1 u + 120
