3. the equation y = 12x 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. carl’s earnings time (h) 3 5 8 10 money earned ($) 45 75 120 150 (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.

a) 45 / 3 = 15, carl earns $15 per hour

b) carl earns 15 and Louis earns 12, so Carl earns more per hour

c) draw a graph with hours across the bottom, and dollars on the vertical.

 use 1, 2, 3, 4, 5, 6 ,7, etc for hours , use 15, 30, 45, 60, 75, 90 , for the Y axis,

 then plot the numbers in the table above and draw a straight line through them
