Comparing the laptop

234 more |
|
|
After |
5 u |
+ 390 |
3x3 =
9 u |
|
234 ÷ 3 = 78
5 x 78 = 390
8 x 78 = 624
Total amount that Nick and Liam had at first
= 8 u + 624 + 12 u
= 20 u + 624
20 u + 624 = 1204
20 u = 1204 - 624
20 u = 580
1 u = 580 ÷ 20 = 29
Amount that Nick had at first
= 8 u + 624
= 8 x 29 + 624
= 232 + 624
= $856
Answer(s): $856
