The plan will be submitted to the judge and, if approved, Hoxworth will be required to pay a trustee the amount that will be required to fund the plan. a. Use linear programming to find the minimum cash settlement necessary to fund the annual payments. Let F = total funds required to meet the six years of payments G1 = units of government security 1 G2 = units of government security 2 Si = investment in savings at the beginning of year i Note: All decision variables are expressed in thousands of dollars. If required, round your answers to five decimal places. For subtractive or negative numbers use a minus sign even if there is a + sign before the blank. (Example: -300) Min F s.t. -1 S1 = 170 -1 S2= 210 -1.075 61 + 0.0655 61 + 0.05125 G2 + 0.0655 61 + 0.05125 G2 + 1.0655 G1 + 0.05125 G2 + 1.05125 G2 + -1 S3= 250 -1 G2 + 1.0325 S1+ 1.0325 S2 + 1.0325 53 + 1.0325 S4 + 1.0325 55+ -1 S4= 310 -1 S5/= 340 -1 S6= 500 Round your answer to the nearest dollar. If an amount is zero, enter "0". Round your answer to the nearest dollar. If an amount is zero, enter "O".

Hoxworth should be willing to pay anything less than $ 20,000 d. Suppose that the annual payments are to be made at the end of each year. Reformulate the model to accommodate this change. Note: All decision variables are expressed in thousands of dollars. If required, round your answers to five decimal places. For subtractive or negative numbers use a minus sign even if there is a + sign before the blank.
