What is the shadow price of one hour of machine time in the Mixing Department?
A、$3
B、$7
C、$10.50
D、$1,193
A、$3
B、$7
C、$10.50
D、$1,193
【参考答案及解析】
If we assume one more hour of machine time in the Mixing Department is available, the new optimal solution is at the intersection of 0.06x + 0.08y = 2,401 and 0.04x + 0.12y = 2,400 Solution by simultaneous equations gives x = 24,030, y = 11,990 ∴ Shadow price of one hour of machine time in the mixing department is $3.
