Suppose that a paving company produces paved parking spaces (q) using a fixed quantity of land (T) and variable quantities of cement (C) and labor (L). The firm is currently paving 1,000 parking spaces. The firm's cost of cement is $3,500.00 per acre covered (r) and its cost of labor is $25.00/hour (w). For the quantities of C and L that the firm has chosen, MPc = 50 and MPI = 5. Is this firm minimizing its cost of producing parking spaces? O a. Yes, since MPc * r = MPI * w O b. No, since MPI/w does not equal MPc/r O c. No, since MPc does not equal MPI. O d. No, since (w) does not equal (r)
