10 u |
| Change |
- $96 |
- 3 u |
| After |
$60 |
7 u |
30% =
30100 =
310 Amount that Mark had left
= 156 - 96
= $60
Total amount that Mark and Peter had left = 60 + 7 u
60 + 7 u = 291
7 u = 291 - 60
7 u = 231
1 u = 231 ÷ 7 = 33
Amount that Peter had at first
= 10 u
= 10 x 33
= $330
Answer(s): $330
