Before |
5 u |
+ 330 |
4x2 = 8 u |
655 |
Change |
- 2 u |
- 132 |
- 1x2 = - 2 u |
|
Comparing the dishwasher and the notebook |
132 more |
|
|
After |
3 u |
+ 198 |
3x2 = 6 u |
|
132 ÷ 2 = 66
3 x 66 = 198
5 x 66 = 330
Total amount that Archie and Owen had at first
= 5 u + 330 + 8 u
= 13 u + 330
13 u + 330 = 655
13 u = 655 - 330
13 u = 325
1 u = 325 ÷ 13 = 25
Amount that Archie had left
= 3 u + 198
= 3 x 25 + 198
= 75 + 198
= $273
Answer(s): $273
