8 u |
+ 440 |
3x3 =
9 u |
984 |
Change |
- 3 u |
- 165 |
- 1x3 =
- 3 u |

Comparing the computer
and the television |
165 more |
|
|
After |
5 u |
+ 275 |
2x3 =
6 u |
|
165 ÷ 3 = 55
5 x 55 = 275
8 x 55 = 440
Total amount that Owen and Ben had at first
= 8 u + 440 + 9 u
= 17 u + 440
17 u + 440 = 984
17 u = 984 - 440
17 u = 544
1 u = 544 ÷ 17 = 32
Amount that Owen had left
= 5 u + 275
= 5 x 32 + 275
= 160 + 275
= $435
Answer(s): $435
