How can you determine the sell price if you are given the regular price for the percent of markdown?

If the markdown is by percentage then take the regular price and multiply it by the percentage as a decimal. Then take that answer and subtract it from the regular price.

Example: $25 with a 20% markdown

25*.20=5
25-5=20

$20 is the sale price

You would need a laid out graph for this but could you provide a picture of just a graph? i can give stepssolve for y.subtract 4xdivide by -1 (opposites)graph slope intercept formcheck each point to see if it’s on the graph
