Question: Using the Library, web resources, and/or other materials, find a real-life application of a linear function. State the application, give the equation of the linear function, and state what the x and y in the application represent. Choose at least two values of x to input into your function and find the corresponding y for each.  State, in words, what each x and y means in terms of your real-life application.  Please see the following example. Do not use any version of this example in your own post. You may use other variables besides x and y, such as x and W depicted in the following example. Be sure to reference all sources using APA style.

The number of women, W , in millions, enrolled in colleges x years after 1984 can be approximated by W = 0.01 x + 3.9. (Blitzer, 2007).  When x = 16, W = 0.01(16) + 3.9  =  4.06.  This implies that in the year 2000 (16 years from 1984) there were approximately 4.06 million women enrolled in colleges. When x = 20, W = 0.01(20) + 3.9 = 4.1.  This implies that in the year 2004 (20 years from 1984) there were approximately 4.1 million women enrolled in colleges.
