What is the correct way to write out the non-linear program for part a? 

Financial planner Minnie Margin has a substantial number of clients who wish to own a mutual fund
portfolio that matches, as a whole, the performance of the Russell 2000 index. Her task is to
determine what proportion of the portfolio should be invested in each of the five mutual funds listed
below so that the portfolio most closely mimics the performance of the Russell 2000 index.

a) Write out the (non-linear) program that would produce a portfolio that most closely mimics the
performance of the Russell 2000 Index.
b) Use Excel's Solver with "GRG Non-Linear" as the solution algorithm: what is the optimal solution,
i.e., what percentages should be invested in each of the five funds?
