The answer is $30.
We know discounted price of the shoes - $24.
We need to find out the original price of the shoes - x.
The discounted price is 80% of the original price (it is said that <span>shoes have been discounted 20%, so 100-20= 80%).
Let's set up a proportion. If $24 is 80%, how much is 100% (the original price):
$24 : 80% = x : 100 %
After crossing the products:
x = $24 * 100% / 80% = $30
Let's just check the result. After the discount of 20%, shoes will cost:
$30 - 20% = $30 - $30*(20/100) = $30 - $6 = $24.
</span><span>The original price of the shoes is $30.</span>
