8. The processing division of the Sunrise Breakfast Company must produce one ton ( 2000 pounds) of breakfast flakes per day to meet the demand for its Sugar Sweets cereal. Cost per pound of the three ingredients is: Government regulations require that the mix contain at least 10% ingredient A and 20% ingredient B. Use of more than 800 pounds per ton of ingredient C produces an unacceptable taste. Determine the minimum-cost mixture that satisfies the daily demand for Sugar Sweets. Can the boundedvariable simplex method be used to solve this problem? 9. Solve the following problem using the two phases of the simplex method: Maximize z=2x1+x2+x3 subject to: 2x1+3x2x32x2+x3+x3x1x10,x20,9,4,=6,x30. Is the optimal solution unique? 10. Consider the linear program: Maximizez=3x1+6x2, subject to: 5x1+7x235x1+2x22x10,x20. Exercises 73 a) Solve this problem by the simplex method. Are there alternative optimal solutions? How can this be determined at the final simplex iteration? b) Solve the problem graphically to verify your answer to part (a). 11.
