    Anybody know how to solve this:

    If the marginal cost function, MC, for a firm is

    MC = 11 + 0.1Q - 21/(Q+1)

    What is the total cost function?

    Do you know how to integrate.

     MC = 11 + 0.1Q  - \frac{21}{Q+1}

     MC = 11 + 0.1Q  -21(Q+1)^-1


     TC = 11Q + 0.05Q^{2} - 21ln(Q+1) + k


    I think that is alright?
