A computer normally cost $640 Its on sale this week for $480 what is the markdown on the price
2 answers:
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%

Step-by-step explanation:
Hello! I hope you are having a nice day.
We can solve this equation in a single step, we just need a bit of theory and a graph.
We can first see that its in form. Which is also known as Slope-Intercept form.
This means that we know the following.
is the y coordinate of the y intercept.
is the slope of the line.
Since we know that, we can see that from our equation that the slope of the line is 3 and the y intercept is (0,-7).
Now that we've gotten that, we can start graphing.
The y intercept is -7 so we can plot (0,-7) as one of our points.
The slope of 3 means that we got up 3 units then right a single unit.
Therefore, another point could be (1,-4).
With our two points, we can create our graph by creating a straight line through those two points and therefore plotting our line.
Cheers!
