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:
[tex]50\times\frac{10}{100}=5[/tex]Now we subtract this from the original price:
[tex]50-5=45[/tex]Therefore, the discount selling price is $45.
