Question

Amir purchased a book at a discount price of $23.10. The original book price was $30.00. What was the percent of the discount on the book?

Answer 1

To calculate the discount percentage, subtract the discount price from the original price, divide the difference by the original price, and multiply by 100. The discount on the book was found to be 23%.

Step-by-step explanation:

The student is asking how to calculate the percent of a discount given the original price and the discount price of a book. To find the discount percentage, we first calculate the discount amount by subtracting the discount price from the original price. Then we divide the discount amount by the original price and multiply by 100 to get the percentage.

Steps to Calculate the Discount Percentage

1. Calculate the discount amount: Original Price - Discount Price.
2. Divide the discount amount by the original price: Discount Amount ÷ Original Price.
3. Multiply the result by 100 to get the discount percentage: (Discount Amount ÷ Original Price) × 100.

In this case, the original price of the book is $30.00 and the discount price is $23.10. Here's how to work it out:

• Discount Amount = $30.00 - $23.10 = $6.90
• Discount Percentage = ($6.90 ÷ $30.00) × 100
• Discount Percentage = 0.23 × 100
• Discount Percentage = 23%
