Mr. Tran has $24,300 to invest, some in bonds and the rest in stocks. He has decided that the money invested in bonds must be at least twice as much as that in stocks. But the money invested in bonds must not be greater than $18,100. If the bonds earn 6%, and the stocks earn 9%, how much money should he invest in each to maximize his interest earned? a. Of the options below, give the number that represents • the correct set of variables ?. the correct objective function description ? • the correct set of constraint descriptions? . 1. the length of the life of the bonds 2. the amount of money available to invest and the restrictions imposed on each investment 3. the amount of money invested in bonds and stocks 4. total interest earned on the investments b. Letting a be the first of the variables listed in the problem statement, and y the second, write the objective function. Z= c, Graph the feasible region on paper, then list the corner points of the feasible region. (Enter ordered pairs (x,y), separated by commas.) d. Test the corner points to find the optimum value of the objective function: . The "winning' corner point is t The optimum value of the objective function is Mr. Tran has $24,300 to invest, some in bonds and the rest in stocks.
