(Ignore income taxes in this problem.) The management of Stanforth Corporation is investigating automating a process. Old equipment, with a current salvage value of $24,000, would be replaced by a new machine. The new machine would be purchased for $426,000 and would have a 6 year useful life and no salvage value. By automating the process, the company would save $147,000 per year in cash operating costs. The simple rate of return on the investment is closest to

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?
