Questions & Step-by-Step Solutions
A store offers a 15% discount on all items. If an item costs $200 after the discount, what was the original price?
Correct Answer: 235.29
Steps
Concepts
Step 1: Understand that a 15% discount means you pay 85% of the original price.
Step 2: Let the original price be represented by 'x'.
Step 3: Write the equation for the selling price after the discount: 0.85 * x = 200.
Step 4: To find 'x', divide both sides of the equation by 0.85: x = 200 / 0.85.
Step 5: Calculate the value of x: x = 235.29.
