5 u |
| Change |
- $28 |
- 3 u |
| After |
$108 |
2 u |
60% =
60100 =
35 Amount that David had left
= 136 - 28
= $108
Total amount that David and Bryan had left = 108 + 2 u
108 + 2 u = 336
2 u = 336 - 108
2 u = 228
1 u = 228 ÷ 2 = 114
Amount that Bryan had at first
= 5 u
= 5 x 114
= $570
Answer(s): $570
