3,000 units 10,000 units 1,250 units 8,000 units 1,000 units Givens: 40 * L + 120 * K min L>0, K >0 s.t. 300 < K.75 * L 25 The marginal product of labor: MPL = .25 * 1.75 The marginal product of capital: MPK = .75 * 5.28 Equation Description: A firm is attempting to minimize total cost subject to sufficiently employing units of labor and units of capital to produce an output level at least as large as a specified output quota. Total cost equals the cost to employing units of labor plus the cost to employing units of capital. A firm's production function is the product of two
terms: the first term is units of capital raised to the.75 power; and, the second term is units of labor raised to the 25 power. The marginal product of labor equals the product of three terms: the first term is.25; the second term is units of capital raised to the .75 power; the third term is units of labor raised to the -75 power. The marginal product of capital equals the product of three terms: the first term is .75; the second term is units of labor raised to the 25 power; the third term is units of capital raised to the -25 power. The wage rate is \$40 per unit of labor. The rental rate is \$120 per unit of capital. The output quota is 300 units. Question: What is minimum total cost? \$94,000 \$80,000 \$48,000 \$32,000 \$26,000 \$100,000 \$8,000 \$72,000

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
