  • 15. Combining a Promotional Code with a Sale

    A shoe store sends you a promotional code that you can use for a discount. (See Example 6.)

    1. What is the percent discount?
    2. The store is having a "60% off" sale on all items. What is the final price when you use the promotional code with the sale?
    • Worked-Out Solution
      1. The discount for the promotional code is

        Compared to original price of $59.80, the discount percent is

      2. When you encounter this type of situation, it is unclear what "60% off" means. Does the store mean 60% off the regular price of $59.80 and then another discount of $14.95? This interpretation seems unlikely.

        More likely is that with the promotional code, the price of the shoes is $44.85. Then, you get to take 60% off of that price.

        So, you should end up paying $17.94.
