    The marginal revenue function at output x is
    MR (x) = 2x + 3.
    Calculate revenue from the sale of 100 products.


    Can't find a way to complete this task, is it somehow connected with derivatives?

    You'll have to do better than that. "Marginal" sounds like it might BE the derivative, no?

    Yes, if I remember correctly (I once had the "pleasure" of teaching a "Math for economics and Business Administration" class) the "marginal revenue" is the derivative of a continuous revenue function ("first difference" if it is defined only for integers). So given that the marginal revenue is $ \displaystyle 2x+ 3$ the revenue from the sale of 100 products is the integral of 2x+ 3 with respect to x from 0 to 100.
