Suppose that Sears has a sale on a portable DVD player. The DVD player was originally
$80. However, the DVD player was marked down at a 25% discount, but today Sears is
having a special 25% off everything in the store, even sales items. What would the cost of the item be today after both discounts? (Explain how you got your answer)
You take the first 25% off and add it to the other 25% off, which would equal 50% off. After that you take 50% off for $80, which would be $40 because half of $80 is $40.
