Question

Isaac went shopping for a new pair of sneakers because of a sale. The price on the tag was $39, but Isaac paid $33.15 before tax. Find the percent discount.

Answer 1

15%

Explanation:

To find the percentage discount, we can use the Discount Formula:

`\boxed{\sf Discount\;Percent=(List\;Price-Selling\;Price)/(List\;Price) * 100}`

The list price is the price on the tag, so $39.

The selling price is the price Isaac paid before tax, so $33,15.

Substitute these values into the formula:

`\sf Discount\;Percent=(39-33.15)/(39) * 100`

`\sf Discount\;Percent=(5.85)/(39) * 100`

`\sf Discount\;Percent=0.15 * 100`

`\sf Discount\;Percent=15\%`

Therefore, the percent discount is 15%.
