Ответ:
$45/3 hours = $15/hour
(b) To see how much Louis makes per hour, simply plug in 1 for the hours value x:
y = 12(1 hours)
y = $12/hour
Thus Carl makes more than Louis.
(c) The equation of Carl's dollars per hour is similar to Louis':
y = 15x
where x is the number of hours he works and y is the number of dollars he earns. Plug in whole number values of hours for x and plot the points (x, y) on a graph.
