Major Motors must produce at least 5,000 luxury cars and 12,000 medium-prices cars. They must also produce at most 30,000 compact cars. The company owns two factories A and B at different locations. Factory A produces 20, 40, and 60 units of luxury, medium, and compact cars per day, respectively, whereas these numbers for Factory B are 10, 30, and 50, respectively. If factory A costs $960,000 per day to operate and B costs $750,000 per day, then 7. Select the correct constraints to the LP you created for this problem. Select one: O a. s.t. 20A + 10B = 5000 40A + 30B = 12000 60A + 50B s 30000 O b. s.t. 20A + 10B s 5000 40A + 30B s 12000 60A + 50B s 30000 A and B20 O c. s.t. 20A + 10B 2 5000 40A + 30B 2 12000 60A + 50B s 30000 A and B 20 O d. s.t. 20A + 10B > 5000 40A + 30B 2 12000 60A + 50B s 30000
