Total |
Before |
5 u |
+ 655 |
8x2 = 16 u |
1285 |
Change |
- 2 u |
- 262 |
- 1x2 = - 2 u |
|
Comparing the washing machine and the dishwasher |
262 more |
|
|
After |
3 u |
+ 393 |
7x2 = 14 u |
|
262 ÷ 2 = 131
3 x 131 = 393
5 x 131 = 655
Total amount that Daniel and Harry had at first
= 5 u + 655 + 16 u
= 21 u + 655
21 u + 655 = 1285
21 u = 1285 - 655
21 u = 630
1 u = 630 ÷ 21 = 30
Amount that Daniel had left
= 3 u + 393
= 3 x 30 + 393
= 90 + 393
= $483
Answer(s): $483
