5 u |
+ 270 |
3x3 =
9 u |
760 |
Change |
- 3 u |
- 162 |
- 1x3 =
- 3 u |

Comparing the laptop
and the dishwasher |
162 more |
|
|
After |
2 u |
+ 108 |
2x3 =
6 u |
|
162 ÷ 3 = 54
2 x 54 = 108
5 x 54 = 270
Total amount that George and Valen had at first
= 5 u + 270 + 9 u
= 14 u + 270
14 u + 270 = 760
14 u = 760 - 270
14 u = 490
1 u = 490 ÷ 14 = 35
Amount that George had left
= 2 u + 108
= 2 x 35 + 108
= 70 + 108
= $178
Answer(s): $178
