A pair of shoes is marked at $90. If a 30% discount is applied, what is the selling price?

Step 1: Identify the marked price of the shoes, which is $90.
Step 2: Determine the discount percentage, which is 30%.
Step 3: Convert the discount percentage into decimal form by dividing by 100. So, 30% becomes 0.30.
Step 4: Calculate the amount of the discount by multiplying the marked price by the discount in decimal form: 0.30 * 90.
Step 5: Perform the multiplication: 0.30 * 90 = 27. This means the discount amount is $27.
Step 6: Subtract the discount amount from the marked price to find the selling price: 90 - 27.
Step 7: Perform the subtraction: 90 - 27 = 63. Therefore, the selling price is $63.
