To calculate the percent discount, we first need to determine the difference between the original price and the price Andy paid, then express that difference as a percentage of the original price.

Here's the formula for percent discount:

$\text{Percent Discount} = \left( \frac{\text{Original Price} - \text{Sale Price}}{\text{Original Price}} \right) \times 100$

Given:

• Original price = 150
• Sale price (what Andy paid) = 112.50

Now, calculate the difference:

$150 - 112.50 = 37.50$

Then, use the formula:

$\text{Percent Discount} = \left( \frac{37.50}{150} \right) \times 100 = 25\%$

So, Andy received a 25% discount.

Here are some related questions for practice:

1. If the cap was priced at $200 and Andy paid $160, what is the percent discount?
2. What would Andy pay if the discount was 30% on the same cap?
3. If Andy had to pay $120 after a 20% discount, what was the original price?
4. How much would Andy save if the discount were 40% instead of 25%?
5. If the cap’s price after a discount was $105, and the original price was $150, what was the discount percentage?

Tip: To calculate percent discount easily, just subtract the sale price from the original price, divide the result by the original price, and multiply by 100.
