We are given that an item costs $50 and has a discount of 10%. To determine the discount selling price we need to subtract 10% of $50 from the original price.
To determine the 10% of the original price we determine the product of $50 by 10/100, like this:
![50*(10)/(100)=5](https://img.qammunity.org/2023/formulas/mathematics/college/mg4p3oesql4cs3oo9vnr3xqmdlhjja89v5.png)
Now we subtract this from the original price:
![50-5=45](https://img.qammunity.org/2023/formulas/mathematics/college/5enkmhc2aujgwgga2rpr1hb2ff1unkqcsw.png)
Therefore, the discount selling price is $45.
