A liquid form of penicillin manufactured by a pharmaceutical firm is sold in bulk at a price of $200 per unit. If the total production cost (in dollars) for x units is C(x) = 500,000 + 80x + 0.003x^2 and if the production capacity of the firm is at most 30,000 units in a specfi ed time, how many units of penicillin must be manufactured and sold in that time to maximize the profit?

the function fot the profit will be the total selling price minus the total production cost. f(x) = 200x - (500,000 + 80x +0.003x^2) f(x) = -0.003x^2 + 120x -500,000 then to find the value of x which will result in maximum profit, you can use the derivative of f(x) f'(x) = 0 f'(x) = -0.006x + 120 = 0 0.006x = 120 x = 20000 then plug x=20000 into f(x) f(x) = -0.003(20000)^2 +120(20000) -500000 that's the maximum profit

oh the question is how many penicillin, the answer is 20000 units. i thought you're asked to find the profit , haha. then just forget about plugging x=20000 into the equation
