Questions & Step-by-Step Solutions

If a product is sold for $80 after a 20% discount, what was the original price?
  • Step 1: Understand that a 20% discount means the product is sold for 80% of its original price.
  • Step 2: Let the original price be represented by 'x'.
  • Step 3: Write the equation for the selling price after the discount: 80 = 0.8 * x.
  • Step 4: To find 'x', divide both sides of the equation by 0.8: x = 80 / 0.8.
  • Step 5: Calculate the value: x = 100.
  • Percentage Discount Calculation – Understanding how to calculate the original price of a product after a discount is applied.
  • Algebraic Manipulation – Using algebra to isolate the variable representing the original price.
