Notice that if C is the amount of card washed, then 5C is the amount of money earned (this is, $5 dollars per car washed).In terms of a function, say x is the number of cars washed. Then the function f(x)=5x models the profit made based on the number of cars washed. This function is similar to the equation above, since they both say that you earn $5 per car washed.
