Where "k" is the constant of proportionality.

Notice that In this case the input values are identified in the table as "Regular Price (dollars)" and the output values are identified as "Sale Price (dollars)" .

Then, in order to find the value of the constant of proportionality, you must pick any input value from the table and its corresponding output value:

Now you must substitute these values into the equation   and then you can solve for "k".

The constant of proportionality is:
