Answer: Third option is correct.
Explanation:
Since we have given that
Selling price of home = $250,000
Rate of commission on each sale she get = 3%
Rate of commission pays for expenses = 25%
So, Firstly amount she get on home sale would be
![(3)/(100)* 250,000\\\\=0.03* 250,000\\\\=\$7,500](https://img.qammunity.org/2019/formulas/mathematics/high-school/e4wolui3xbi0v1grv52svr49w4pyk4dcxr.png)
Amount after paying for expenses would be
![7500* (100-25)/(100)\\\\=7500* (75)/(100)\\\\=7500* 0.75\\\\=5,625](https://img.qammunity.org/2019/formulas/mathematics/high-school/qpcmxta417y3ai9gg0o3ss9oxzo0ylloou.png)
Hence, Multiply $250,000 by 0.03, and then multiply again by 0.75 is correct.
Therefore, Third option is correct.
