The usual price of a school bag was 30 alic bought it for 25 at a sale what was the percentage discount Alice received

To calculate the percentage discount Alice received, we can use the formula:

Percentage Discount = (Discount Amount ÷ Original Price) × 100

The discount amount is the difference between the original price and the sale price:

Discount Amount = Original Price - Sale Price

Original Price = $30
Sale Price = $25

Discount Amount = $30 - $25 = $5

Now we can substitute the values into the formula:

Percentage Discount = (5 ÷ 30) × 100
Percentage Discount = 0.1667 × 100
Percentage Discount = 16.67%

Therefore, Alice received a discount of 16.67%.
