Deborah inherited a large sum of money; she wants to use a portion of this money to set up a trust fund for her two children. The trust fund has two investment options: 1) a bond fund and 2) a stock fund. The projected returns over the life of the investments are 6% for the bond fund and 10% for the stock fund. Whatever portion of the inheritance she finally decides to commit to the trust fund, she wants to invest at least 30% of the amount in the bond fund. In addition, she wants to select a mix that will enable her to obtain a total return of at least 7.5%.
