Transmission over finite potential well?

  1. 1. The problem statement, all variables and given/known data
    A beam of 500 electrons per second with kinetic energy W1=3eV passes onto potential well (its depth is 5eV and width is 0,3nm). How many electrons per second are transmitted through the well?
    (It's a poor translation, sorry, but I hope you get the idea of the problem)

    3. The attempt at a solution
    As far as I understand, this is a problem of finding transmission (T) over finite potential well. I guess the answer would be 500*T . But I can't find any equations to calculate T, and my attempts to formulate it were no good. Can anyone give me at least a hint?
