Answer:
If a laptop was originally sold for $975. The laptop is now on sale for $828.75. The percent markdown will be 15%
Using this formula
Percent markdown =(Original cost -Current cost)/ Original Cost × 100
Let plug in the formula
Percent markdown=($975 - $828.75) / $975 ×100
Percent markdown=146.25/975 ×100
Percent markdown=15%
Inconclusion If a laptop was originally sold for $975. The laptop is now on sale for $828.75. The percent markdown will be 15%
