Steps
Concepts
Step 1: Identify the cost price of the laptop, which is $800.
Step 2: Calculate the loss percentage, which is 10%.
Step 3: Find out how much money 10% of $800 is. To do this, multiply $800 by 0.10 (which is the decimal form of 10%).
Step 4: Calculate 10% of $800: 800 * 0.10 = $80.
Step 5: Subtract the loss ($80) from the cost price ($800) to find the selling price.
Step 6: Selling Price = Cost Price - Loss = 800 - 80 = $720.
