 Example 1: The market price of an article is \$18,000. By selling it at a discount of 20% the loss is 4% find its cost price. Solution: Market price = \$18,000 and discount = 20% Therefore, Selling price = M.P(100 - d%) / 100 = 18,000 (100 - 20) / 100 = 18,000 * 80 / 100 Selling price = 14,400 Selling price = \$14,400 and loss = 4% Therefore, Cost price = (Selling price * 100) / (100 - l%) = (14,400 * 100) / (100-4) = 1,440,000 / 96 Cost price = \$15,000 Example 2: Jake wants to buy a skateboard. The regular price of the board is \$135. Suppose it is on sale at a 25% discount. Find the sale price of the skateboard. Let d represent discount. d = 0.25(135) = 33.75 Selling price = 135 - 33.75 = 101.25 Directions: Solve the following questions. Also write at least 5 examples of your own.
