Answer: Option 'C' is correct.
Explanation:
Since we have given that
Cost function is defined as C = 6n+200
and Revenue function is defined as R = 14n
Since we need to find the break even point.
And we know that at break even point, C(x)= R(x).

So, At n=25, there is the break even point for this corn stand.
Hence, Option 'C' is correct.
