The given table shows how Bryan is paid at his job as tour guide.

Number of tours given	$1$	$2$	$3$	$4$	$5$	$6$	$7$
Amount Paid in Commission $($)$	$8$	$16$	$24$	$32$	$40$	$48$	$56$

Let $C$ be the amount paid in commission per tour, and $n$ the number of tours Bryan gives. The amount he is paid depends on the number of tours. Therefore, $C$ is the dependent variable, and $n$ the independent variable. We see in the table that Bryan earns $$ 8$ per tour. $C (n) = 8 n$
