Question 454825: This problem is impossible! My pivot elements are not working out correctly. I have it all messed up and now I'm lost. Can anyone help me? Thank you in advance!
An investor has at most $30,000 to invest in government bonds, mutual funds, and money market funds. The average yields for government bonds, mutual funds, and money market funds are 4%, 9%, and 11%, respectively. The investors policy require that the total amount invested in mutual and money market funds not exceed the amount invested in government bonds. How much should be invested in each type of investment in order to maximize the return? What is the maximum return in the first year?
