  • Calculus: revenue, marginal revenue, and population... HELP!?

    If anyone could please help me with these problems. I have homework questions that are like them and I am studying for a test and don't understand them at all!

    The revenue R (in dollars) from renting x apartments can be modeled by the function below:

    R = 6x (100 + 48x - x^2)

    a. Find the additional revenue when the number of rentals is increased from 14 to 15.

    b. Find the marginal revenue when x = 14.

    THIS ONE:

    The population P (in thousands) of a country can be modeled by the function below, where t is time in years, with t = 0 corresponding to 1980. (Note: I used ^ to stand for to the power).

    P= -14.78t^2 + 793.4t + 183,716

    a. Evaluate P for t = 0, 10, 15, 20, and 25.

    b. Evaluate dP/dt for the same values as in part (a).
