Before |
8 u |
+ 288 |
3x5 = 15 u |
794 |
Change |
- 5 u |
- 180 |
- 1x5 = - 5 u |
|
Comparing the washing machine and the home theater system |
180 more |
|
|
After |
3 u |
+ 108 |
2x5 = 10 u |
|
180 ÷ 5 = 36
3 x 36 = 108
8 x 36 = 288
Total amount that Daniel and Ian had at first
= 8 u + 288 + 15 u
= 23 u + 288
23 u + 288 = 794
23 u = 794 - 288
23 u = 506
1 u = 506 ÷ 23 = 22
Amount that Daniel had at first
= 8 u + 288
= 8 x 22 + 288
= 176 + 288
= $464
Answer(s): $464
