Before |
5 u |
+ 515 |
3x2 = 6 u |
801 |
Change |
- 2 u |
- 206 |
- 1x2 = - 2 u |
|
Comparing the television and the laptop |
206 more |
|
|
After |
3 u |
+ 309 |
2x2 = 4 u |
|
206 ÷ 2 = 103
3 x 103 = 309
5 x 103 = 515
Total amount that Sam and Flynn had at first
= 5 u + 515 + 6 u
= 11 u + 515
11 u + 515 = 801
11 u = 801 - 515
11 u = 286
1 u = 286 ÷ 11 = 26
Amount that Sam had left
= 3 u + 309
= 3 x 26 + 309
= 78 + 309
= $387
Answer(s): $387
