Part I: Modeling Questions (20 points) Aunt Bea’s Brownie Company makes three products: a regular fudge brownie mix, a sugar free fudge brownie mix, and ready to microwave brownie mix. The regular brownie mix generates a profit of \$100 per case sold. Sugar-free brownies have a profit of \$120 per case and the microwave brownie mix have a profit of \$200 per case. The microwave brownie mix is not as popular as the other two mixes so the production of it is limited to no more than 25% of the total cases of brownie mixes made each week. The main ingredients in brownies are sugar, flour and cocoa. The sugar free brownie mix is made with Splenda instead of sugar. The table below shows availability and the number of pounds of each ingredient needed for a case of each mix Regular Sugar Free Microwave Availability Ingredient lbs/case lbs/case lbs/case (pounds) Sugar 40 0 30 5000 Splenda 0 20 0 1000 Flour 35 45 25 7000 Cocoa 10 8 8 1800 The same mixing machine is used for all mixes.
