Question

Craig works at an appliance store. He earns a fixed salary of $1,000 every 2 weeks. He also earns a $50 commission on each appliance he sells. Craig's earnings in dollars, y,can be represented as a function of the number of appliances he sells, x. Which graph represents Craig's earnings during a two week period in which he sells no more than 20 appliances?

Answer 1

 

The function is y= 50x + 1000

 

This is graphically represented by a line with slope=50 and y intercept= 1000

 

The restriction in this particular period is that he sells no more than 20 appliances meaning x<20. So the solution will be a segment on the line from x=0 to x=20. Excluding (20, 2,000), which is the point of intersection of x=20 and the line representing earnings.

 

Hope this helps!
