    help please.

    please help me to solve this problem.

    An analyst has found that a company’s costs and revenues in dollars for one product are given by C(x)=15x+250 and R(x) 45x+x^4/100 respectively, where x is the number of items produced and sold. Find the marginal profit when 10 units are produced and sold.

    thank you so much.

    What is the difficulty here?

    Profit is:

    P(x)=R(x)-C(x)

    and the marginal profit at production level z is:

    \left. \frac{d}{dx}P(x)\right|_{x=z}

    As the profit is a polynomial in x you should have no problem computing the required magrinal profit.
