Answer:
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.
