Questions & Step-by-Step Solutions

If a product is sold for $80 after a discount of 20%, what was the original price?
  • Step 1: Understand that the product is sold for $80 after a discount of 20%.
  • Step 2: Let the original price be represented by 'x'.
  • Step 3: A 20% discount means the customer pays 80% of the original price.
  • Step 4: Write the equation for the price after the discount: 0.8 * x = 80.
  • Step 5: To find 'x', divide both sides of the equation by 0.8: x = 80 / 0.8.
  • Step 6: Calculate the right side: 80 divided by 0.8 equals 100.
  • Step 7: Therefore, the original price of the product is $100.
  • Percentage Discount Calculation – Understanding how to calculate the original price of a product after a percentage discount has been applied.
  • Algebraic Manipulation – Using algebra to solve for the unknown variable (original price) in an equation.
