calculus The profit generated from producing and selling x floopers is given by P(x) = -0.01 x**2 + 50 x - 8000 dollars. Find the marginal profit when 4000 floopers are being produced

    marginal profit is given by P'(x) what do you have for the derivative of P(x) ?

    I'm not asking you to give me more info, I'm asking you to take the derivative of P(x) to find the marginal profit function P'(x)

    does that mean you don't know how to take the derivative of P(x) ?

    I know how I was just moving to a different problem since you left the question

    f'(x) = -0.0001x+50

    the first term is wrong -0.01x^2 derivative is -0.01(2x)=-0.02x

    you wrote -0.01x^2 in the problem in any event, find the derivative and then plug in the given value f'(4000)=?

    so f'(x)= -0.01(4000)+50

    I'm not sure, you told me the function was a few different things, but at least the idea is right: find derivative, plug in number
