The total cost incurred by time t in the production of a certain commodity is f (t) dollars. The number of products produced by time t is g (t) units. What does the function f (t) / g (t) represent?

f (t) / g (t) represents the average cost of producing a unit of commodity between the time frame 0-t.

Step-by-step explanation:

f (t) is cost in dollar while g (t) is in unit. f (t) / g (t) will be cost per unit.

In other words f (t) / g (t) is the total cost spent in time t divided by the amount of commodity produced in units produced in time t.
