A man buys a watch for $80 and sells it for $100. What is his profit percentage?

Step 1: Identify the cost price of the watch, which is $80.
Step 2: Identify the selling price of the watch, which is $100.
Step 3: Calculate the profit by subtracting the cost price from the selling price: Profit = Selling Price - Cost Price = 100 - 80.
Step 4: The profit is $20.
Step 5: To find the profit percentage, use the formula: Profit Percentage = (Profit / Cost Price) × 100.
Step 6: Substitute the values into the formula: Profit Percentage = (20 / 80) × 100.
Step 7: Calculate the profit percentage: (20 / 80) = 0.25, then multiply by 100 to get 25%.
Step 8: The profit percentage is 25%.
