Please help me you guys, this is the 3rd time I have posted this question.
Is anybody going to help me with this problem?
A widget factory has fixed costs of 35 billion dollars and variable costs of 781 million dollars per widget. The revenue (in $ billions) from selling x number of widgets is given by the following for x between 0 and 60.
R(x) = 0.11(60x - x^2)
What is the marginal profit (in $ billions per widget) at production level x = 19 widgets? (Give your answer correct to 3 decimal places.)
$ _______ billion per widget
