The cost, C (in dollars) to produce g gallons of a chemical can be expressed as C=f (g). Using units, explain the meaning of the following statements in terms of the chemical. (a) f (400) = 700 The statement f (400) = 700 means

To produce 400 gallons of a chemical, it costs 700 dollars.

Step-by-step explanation:

We have that:

The cost, C (in dollars) to produce g gallons of a chemical can be expressed as C=f (g).

The interpretation is:

To produce g gallons of a chemical it costs C dollars.

So

f (400) = 700

This means that to produce 400 gallons of a chemical, it costs 700 dollars.
