C C C This is a typical blending model, where three inputs must be blended to produce four outputs. Any inputs not used in producing outputs can be sold for the salvage values shown. The percentages of chemical A in the outputs must be within the limits in rows 12 and 13. Which of the following is true of the optimal solution? a. For at least two of the outputs, more is produced than is required. Blending model Data on inputs Input 1 Input 2 Input 3 Data on outputs Unit selling price Min % chemical A Max % chemical A Required Blending plan Input 1 Input 2 Input 3 Constraints on chemical A Minimum Actual Maximum Monetary values Revenue from outputs Revenue from inputs Total revenue b. There is some left over of at least two inputs, which is sold at the salvage values. c. All of the products are at their upper limits with respect to chemical A. d. All of these choices are true. Salvage value $1.25 $1.40 $1.60 Output 1 $1.50 0% 5% 1000 Output 1 Output 1 % chemical A 8% 3% 4% Output 2 $2.30 4% 6% 500 Output 2 Output 2 Available 1500 1200 900 Output 3 $1.90 2% 4% 600 Output 3 Output 3 Output 4 $2.70 1% 5% 800 Output 4 Output 4
