Multiple Choice

The cost of sending an overnight package from New York to Atlanta is $9.80 for up to, but not including, the first pound and $3.50 for each additional pound (or portion of a pound) . A model for the total cost $C$ of sending the package is $C = 9.80 + 3.50$$\lfloor x \rfloor,$ $x > 0,$ where $x$ is the weight of the package (in pounds) . Sketch the graph of this function. Note that the function $\lfloor x \rfloor$ is the greatest integer function.
