8
Step-by-step explanation:
it is not longer then the red line or equal but is bigger then the green line so there is how i got 8
For this case we have the following equation:

Rewriting we have:

Dividing by 2 to both sides of the equation:

We apply the quadratic formula:

We have to:

Substituting:

Thus, we have two roots:

ANswer:

Given cost function is
c(x) =
(20 ≤ x ≤ 400)
where x is the number of thousands of square feet
total revenue will be $0.2 million dollars per thousand square feet
Revenue is 0.2 millions per thousand square feet. we know x is the number of thousand of square feet
So R(x) = 0.2x
We know Profit = Revenue - Cost
P(x) = R(x) - C(x)


combine like terms

Profit function is

Answer:
Yes
Step-by-step explanation:
