- Neave

Ivory |
Neave |
Before |
1 u |
5 u |
Change |
+ $128 |
- $128 |
After |
1 u + $128 |
5 u - $128 |
The amounts that Neave and Ivory had in the end are the same.
5 u - 128 = 1 u + 128
5 u - 1 u = 128 + 128
4 u = 256
1 u = 256 ÷ 4 = 64
Amount that Ivory had at first
= 1 u
= $64
Amount that Neave had at first
= 5 u
= 5 x 64
= $320
Answer(s): (a) $64; (b) $320
