Total |
Before |
9 u |
+ 414 |
6x5 = 30 u |
1701 |
Change |
- 5 u |
- 230 |
- 1x5 = - 5 u |
|
Comparing the refrigerator and the washing machine |
230 more |
|
|
After |
4 u |
+ 184 |
5x5 = 25 u |
|
230 ÷ 5 = 46
4 x 46 = 184
9 x 46 = 414
Total amount that Ken and Julian had at first
= 9 u + 414 + 30 u
= 39 u + 414
39 u + 414 = 1701
39 u = 1701 - 414
39 u = 1287
1 u = 1287 ÷ 39 = 33
Amount that Ken had left
= 4 u + 184
= 4 x 33 + 184
= 132 + 184
= $316
Answer(s): $316
