Express your answer in terms of z.) (x, y, z) = (b) If $16,000 is invested at 10%, how much should be invested at each of the other rates? 8% $ 7% $ What if $32,000 is invested at 10%? 8% $ 7% $ (c) What is the minimum amount that should be invested at 7%? $ In this case how much should be invested at the other rates? 8% $ 10% $ (d) What is the maximum amount that should be invested at 7%? $ In this case how much should be invested at the other rates?
