Verified step by step guidance1
Identify the original price of the shoes, which is given as \$80.
Recognize that the discount is 25%, which means you need to find 25% of the original price.
Convert the percentage to a decimal by dividing 25 by 100, so 25% becomes 0.25.
Calculate the discount amount by multiplying the original price by the decimal form of the percentage: \(80 \times 0.25\).
Find the sale price by subtracting the discount amount from the original price: \(80 - (80 \times 0.25)\).
