An investor has $621,000 to invest in bonds.  Bond A yields an average of 8% and the bond B yields 7%.  The investor requires that at least 5 times as much money be invested in bond A as in bond B.  You must invest in these bonds to maximize his return.  This can be set up as a linear programming problem.  Introduce the decision variables: x= dollars invested in bond Ay= dollars invested in bond B Compute x+y. $                       .  Round to the nearest cent.   Investor Matt has $152,000 to invest in bonds.  Bond A yields an average of 9.2% and the bond B yields 8.4%.  Matt requires that at least 4 times as much money be invested in bond A as in bond B.  You must invest in these bonds to maximize his return.  What is the maximum return? $                       per year.  Round to the nearest cent.   Investor Dan has $607,000 to invest in bonds.  Bond A yields an average of 8.5% and the bond B yields 8.4%.  Dan requires that at least 4 times as much money be invested in bond A as in…

Answer the question using linear programming simplex method. A Western shop wishes to purchase 300 felt and 200 straw cowboy hats. Bids have been received from the wholesalers. Beta Hatters has agreed to supply not more than 200 hats. Kappa Hatters not more than 250, Delta Hatters not more than 150. The owner of the shop has estimated that his profit per hat sold from Beta Hatters would be P30/felt and P40/straw, from Kappa Hatters P38/felt and P35/straw, and from Delta Hatters P40/felt nad P36/straw. The Western shop wants to determine maximum profit.
