The current rate on government securities is 9%.
In making its decision, the planning committee must satisfy certain legal requirements and bank policies.
These can be summarized by the following set of conditions.
The amount allocated to secured loans must be at least four times the amount allocated to
unsecured loans.
The total value of car and home loans should be no more than 20% of the value of all secured
loans.
The value of student loans should be no more than 30% of unsecured loans.
The amount allocated to government securities should be at least 10%, but no more than 20%,
of available funds.
• The amount allocated to vacation loans must not exceed 10% of all loans.
The bank has $5 million available for loans and investments in the next month. Formulate a linear
programming model that will enable the planning committee to determine the optimal allocation of funds
if the objective is to maximize the annual return, given the preceding list of conditions.
