Before |
5 u |
+ 395 |
8x2 = 16 u |
899 |
Change |
- 2 u |
- 158 |
- 1x2 = - 2 u |
|
Comparing the television and the dishwasher |
158 more |
|
|
After |
3 u |
+ 237 |
7x2 = 14 u |
|
158 ÷ 2 = 79
3 x 79 = 237
5 x 79 = 395
Total amount that Oscar and Glen had at first
= 5 u + 395 + 16 u
= 21 u + 395
21 u + 395 = 899
21 u = 899 - 395
21 u = 504
1 u = 504 ÷ 21 = 24
Amount that Oscar had left
= 3 u + 237
= 3 x 24 + 237
= 72 + 237
= $309
Answer(s): $309
