Questions & Step-by-Step Solutions
If a product is sold for $240 after a discount of 20%, what was the original price?
Step 1: Let the original price be represented by 'x'.
Step 2: The product is sold for $240 after a 20% discount.
Step 3: A 20% discount means the selling price is 80% of the original price.
Step 4: Write the equation for the selling price: Selling Price = Original Price - Discount.
Step 5: Substitute the values: 240 = x - (20% of x).
Step 6: Convert 20% to a decimal: 20% = 0.2, so the equation becomes 240 = x - 0.2x.
Step 7: Combine like terms: 240 = 0.8x.
Step 8: To find 'x', divide both sides by 0.8: x = 240 / 0.8.
Step 9: Calculate the value: x = 300.
Step 10: The original price is $300.
