The equation y= 13.5x describes the amount of money Louis earns, where x is the number of hours he works and y is the amount of money he earns. The table shows the amount of money Carl earns for different numbers of hours worked.

A) How much money does Carl earn per hour? Show your work.
B) Who earns more per hour? Justify your answer.
C) Draw a graph that represents Carl’s earnings over time in hours. Remember to label the axes.
D) Is this graph proportional?
