Answer:
14%
Explanation:
In this question, we have to find the percent markdown of the cost of the DVD player.
We know that the original price was $175.80, and now it is $150.65
To find the markdown, lets set this up as a proportion:

First, lets find how much money was downed due to the sale. Do this by subtracting the sale cost from the original.
175.80 - 150.65 = $25.15
Since we now know our markdown cost, we can plug in the information to our proportion:

Since we're solving for the percent markdown, we will replace the %down with an x, since we will be solving for x.
Solve for x:

Cross multiply.

Divide both sides by 175.80

When you round the decimal to the nearest whole, you would get a markup of 14%
