A sign says that the price marked on all music equipment is at a discount for 30% off. You buy an electric guitar for the same price of $315. The original pice is $450.What was the percent of discount of the original price.

Answer 1

30%

Step-by-step 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

`(135)/(450)*100=0.3*100=30\text{ \%}`

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