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.
14 of Adam's stickers is 10 less than
19 of Bryan's stickers.
Let
14 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)
14 of Adam's stickers = 1 u
44 of Adam's stickers = 4 u
(b)
19 of Bryan's stickers =
14 of Adam's stickers + 10
19 of Bryan's stickers = 1 u + 10
99 of Bryan's stickers = 9(1 u + 10) = 9 u + 90
(c)
Total number of stickers
= 4 u + 9 u + 90
= 13 u + 90
(d)
Difference in the number of stickers between Bryan and Adam
= 9 u + 90 - 4 u
= 9 u - 4 u + 90
= 5 u + 90
Answer(s): (a) 4 u; (b) 9 u + 90; (c) 13 u + 90; (d) 5 u + 90
