Explanation:
Given
![Market\ Price = m](https://img.qammunity.org/2022/formulas/mathematics/college/nbcxhusu6a27eqijz8eiapltouu6esqtx1.png)
![Discount = 50\%](https://img.qammunity.org/2022/formulas/mathematics/college/g7k9182idcfbsjd9keoc5apnef74pszolt.png)
Selling Price = 3 * Amount she paid
Required
Determine the selling price
If she gets a discount of 50%, then she pays 50% (i.e. 100 - 50%).
So, the amount she paid is:
![Amount = 50\% * Market\ Price](https://img.qammunity.org/2022/formulas/mathematics/college/iiewqrq00rgoyalbik2jqan4arjn5mfcde.png)
![Amount = 50\% * m](https://img.qammunity.org/2022/formulas/mathematics/college/dnw8brpwamor1w0odostbvs1facwuylc5h.png)
![Amount = 0.5* m](https://img.qammunity.org/2022/formulas/mathematics/college/fbzzkqg38zhhzl4b6muqq31ljgwm9as2kx.png)
![Amount = 0.5m](https://img.qammunity.org/2022/formulas/mathematics/college/67n9hmyzw37t2ffhat990f82oysqgap82v.png)
She sells at three times that amount.
So, the selling price is:
![Selling\ Price = 3 * 0.5m](https://img.qammunity.org/2022/formulas/mathematics/college/tkcv7p6ewfwlffagdyklq0hbatzpmlcqzx.png)
![Selling\ Price = 1.5m](https://img.qammunity.org/2022/formulas/mathematics/college/gfn6l8u5aoo962d7awoknreuaet3sqvssp.png)
