Traditions clothing store is having a sale. Shirts that were regularly priced at $20 are on sale $17. Explain how to find the discount offered for the price of the shirts?

Step-by-step explanation:

Let x represent the discount in percentage offered for the price of the shirts.

The regular price of the shirts was $20

The price for which the shirt was offered for sale is $17 which also represents the discounted price.

The discount would be

20 - 17 = $3

The percentage discount would be

The discount / the regular price * 100%.

Therefore,

% discount = 3/20 * 100 = 0.15 * 100

= 15%
