2 u - $30 |
1 u + $30 |
$267 |
Change |
+ $30 |
- $30 |
|
After |
2 u |
1 u |
$267 |
(a)
Total amount that Ken and Oscar have in the end
= 1 u + 2 u
= 3 u
3 u = 267
1 u = 267 ÷ 3 = 89
Amount that Oscar has at first
= 1 u + 30
= 89 + 30
= $119
(b)
Amount that Ken has at first
= 267 - 119
= $148
Answer(s): (a) $119; (b) $148
