We are told that the price of a pair of shoes is $120. If they are sold at a 10% off then we can calculate the final price by subtracting the 10% of the price from the original price, that is:
[tex]P=120-120\times\frac{10}{100}[/tex]Solving the percentage we get:
[tex]P=120-12[/tex]Solving the operations:
[tex]P=108[/tex]Therefore, the sale price is $108.
