The Cost C(q)(in Dollars)of Producing a Quantity Q of a Certain

Short Answer

The cost C(q)(in dollars)of producing a quantity q of a certain product is shown in the graph below.Suppose that the manufacturer can sell the product for $2.50 each (regardless of how many are sold), so that the total revenue from selling a quantity q is R(q)= 2.5q.The difference $\pi(q)=R(q)-C(q)$ is the total profit.Let $90$ be the quantity that will produce the maximum profit.What is $C^{1}\left(q_{0}\right)$ ?
