To determine the sale price of the shirt after applying a 20% discount, you start by calculating the amount that will be discounted.

First, find 20% of the original price, which is $30. This is done by converting the percentage to a decimal and multiplying by the original price:

20% as a decimal is 0.20. Thus, you perform the calculation:

0.20 × $30 = $6.

This means the discount on the shirt is $6. Next, subtract this discount from the original price:

$30 - $6 = $24.

Therefore, the sale price of the shirt after applying the discount is $24. This clearly illustrates how to calculate a sale price based on a percentage discount, making the calculation straightforward and easy to follow.
