Comparing the washing machine

135 more |
|
|
After |
5 u |
+ 225 |
4x3 =
12 u |
|
135 ÷ 3 = 45
5 x 45 = 225
8 x 45 = 360
Total amount that Daniel and Ivan had at first
= 8 u + 360 + 15 u
= 23 u + 360
23 u + 360 = 1004
23 u = 1004 - 360
23 u = 644
1 u = 644 ÷ 23 = 28
Amount that Daniel had at first
= 8 u + 360
= 8 x 28 + 360
= 224 + 360
= $584
Answer(s): $584
