A shirt is marked at $80. If a discount of 20% is offered, what is the selling price?

Step 1: Identify the marked price of the shirt, which is $80.
Step 2: Determine the discount percentage, which is 20%.
Step 3: Convert the discount percentage into decimal form by dividing by 100. So, 20% becomes 0.20.
Step 4: Calculate the amount of the discount by multiplying the marked price by the discount in decimal form: 0.20 * 80.
Step 5: Perform the multiplication: 0.20 * 80 = 16. This means the discount amount is $16.
Step 6: Subtract the discount amount from the marked price to find the selling price: 80 - 16.
Step 7: Perform the subtraction: 80 - 16 = 64. Therefore, the selling price is $64.
