Comparing the dishwasher
and the laptop |
234 more |
|
|
After |
2 u |
+ 156 |
2x3 =
6 u |
|
234 ÷ 3 = 78
2 x 78 = 156
5 x 78 = 390
Total amount that Owen and Valen had at first
= 5 u + 390 + 9 u
= 14 u + 390
14 u + 390 = 740
14 u = 740 - 390
14 u = 350
1 u = 350 ÷ 14 = 25
Amount that Owen had left
= 2 u + 156
= 2 x 25 + 156
= 50 + 156
= $206
Answer(s): $206
