Harris |
Robert |
| Before |
1 u |
4 u |
| Change |
+ 190 |
+ 82 |
| After |
1 u + 190 |
4 u + 82 |
The amount that Harris and Robert had in the end is the same.
1 u + 190 = 4 u + 82
4 u - 1 u = 190 - 82 = 108
3 u = 108
1 u = 108 ÷ 3 = 36
Amount that Robert had at first
= 4 u
= 4 x 36
= $144
Answer(s): $144
