Given:
Selling price of radio for Masada = 63,000
Loss = 10%
To find:
The amount of money Masada paid for the radio?
Solution:
Let x be the amount of money Masada paid for the radio.
According to the question,
![x-10\%\text{ of }x=63000](https://img.qammunity.org/2021/formulas/mathematics/high-school/kcn84srb6idmqxm033mgcb5pupav97fomx.png)
![x-(10)/(100)x=63000](https://img.qammunity.org/2021/formulas/mathematics/high-school/6ux26bzyiz2buyagrcje24deua84isctdk.png)
![x-0.1x=63000](https://img.qammunity.org/2021/formulas/mathematics/high-school/ixxqyyp9qvnp23pugl5siqei007xcoe5x6.png)
![0.9x=63000](https://img.qammunity.org/2021/formulas/mathematics/high-school/8fcd7rqezemx6u7qejynip3h2n7bzxs8jj.png)
Divide both sides by 0.9.
![x=(63000)/(0.9)](https://img.qammunity.org/2021/formulas/mathematics/high-school/rpazy4oq63gpelfesqy3etp84loubjxh05.png)
![x=70000](https://img.qammunity.org/2021/formulas/mathematics/high-school/obhjk4nsqacr8nd7os3vnp0mo8bguz1d79.png)
Therefore, Masada paid 70,000 for the radio.
