$264 |
10 u |
Change |
- $71 |
- 3 u |
After |
$193 |
7 u |
30% =
30100 =
310 Amount that Ahmad had left
= 264 - 71
= $193
Total amount that Ahmad and Ian had left = 193 + 7 u
193 + 7 u = 305
7 u = 305 - 193
7 u = 112
1 u = 112 ÷ 7 = 16
Amount that Ian had at first
= 10 u
= 10 x 16
= $160
Answer(s): $160
