To determine the cost of proportionality, we can use the given information that Sarah earns $320 for working 40 hours.

Let's use the variables $M for the amount of money Sarah earns and $H for the number of hours worked.

Based on the given information, we can set up the proportion:

$320/40 = $M/$H

Simplifying the left side of the proportion gives us:

$8 = $M/$H

So, for each hour worked, Sarah earns $8.
