A coal mine cost $1,003,000 and is estimated to hold 50,000 tons of coal. There is no residual value. During the first year of operations, 6,000 tons are extracted and sold. Calculate depletion per unit. (Round your answer to the nearest cent.)

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 comma 600.003,600.00 per acre covered (c) and its cost of labor is $35.0035.00/hour (w). for the quantities of c and l that the firm has chosen, mp subscript upper c baseline equals 60mpc=60 and mp subscript upper l baseline equals 7mpl=7. is this firm minimizing its cost of producing parking spaces?
