Respuesta :

Answer:

30%

Explanation:

We will find what was the percent of the discount. So, first, we need to find the difference between the original price and the price that you pay.

$450 - $315 = $135

Now, we can calculate how much $135 represents in percentage to the original prices as follows

[tex]\frac{135}{450}\times100=0.3\times100=30\text{ \%}[/tex]

Therefore, the percent of discount of the original price was 30%
