Homework Help: Economics math problems

  1. Mar 12, 2008 #1
    1. The problem statement, all variables and given/known data
    A friend gave me these problems to solve, believing they were calculus problems, which I did study over 10 years ago. They seem more related to economics, which I did not study.

    2. Relevant equations

    3. The attempt at a solution
    The only attempt I made was for Q3.

    Y= t^2 + (10-t)^2 + t(10-t)
    = t^2 + 100 - 20t + t^2 + 10t - t^2
    = 100 - 10t + t^2

    But do not know if this means it exhibit skill-complementarities or not.

    Any help is appreciated, and thanks in advance.
