Acomputer normally cost $640 its on sale this week for $480 what is the markdown on the price

Answer is provided in the image attached.

For this case we have that the original price is $ 640. If this week is at $ 480 then the discount is:

$ 640- $ 480 = $ 160

Thus, the discount is $ 160.

We look for the percentage by making a rule of three:

$ 640 -------------> 100%

$ 160 -------------> x

Where "x" represents the discount percentage:

Thus, the discount percentage is 25%

25%
