Stella is a sales person who sells computers at an electronics store. She makes a base pay amount each day and then is paid a commission as a percentage of the total dollar amount the company makes from her sales that day. Let P represent Stella's total pay on a day on which she sells x dollars worth of computers. A graph of PP is shown below. Write an equation for P then state the y-intercept of the graph and determine its interpretation in the context of the problem. P=
The y-intercept of the function is which represent what?
