A factory makes two different types of product: ordinary and premium. Each product is made using three different machines: A, B, and C Each ordinary product needs 3 minutes on machine A, 10 minutes on machine B. It costs $8 to make a ordinary product. Each premium product needs 7 minutes on machine A, 4 minutes on machine B, and 11 minutes on machine C. It costs $14 to make a premium product. Machine A is available for 6 hours a day, machine B for 5 hours a day, and machine C for 8 hours a day. The budget is $700 per day. The factory must make: At least 35% of total production must be premium product. Number of premium products must be less than twice the number of ordinary products.
