- $890 |
- $190 |
After |
3 u - $890 |
1 u - $190 |
(a)
The amounts that Nicole and Linda had in the end are the same.
3 u - 890 = 1 u - 190
3 u - 1 u = 890 - 190
2 u = 700
1 u = 700 ÷ 2 = 350
Amount that Linda had at first
= 1 u
= $350
(b)
Amount that Nicole had at first
= 3 u
= 3 x 350
= $1050
Answer(s): (a) $350, (b) $1050
