Tianyu owns a fried chicken restaurant in downtown Berkeley. The restaurant needs employees (L) for operation and raw meat preprocessing and fryers (K) for cooking. The production function of drumsticks 1 2 2 1 is Q = 30KL5 with MPK = 20 (if and MPL = 10 (i) 3 where Q denotes the number of fried drumsticks per hour. Tianyu pays his employees $25 per hour and $50 per hour to rent the fryers. Using Tianyu's marketing and economic instinct, he determines that it is best for him to produce 300 drumsticks per hour and charge $5 per drumstick. A.
