3. A capitalist owns a machine that will last for two more years. The good the machine helps produce will yield revenue of $50.000 and $40,000 with costs of $35,000 and $39,000. It will have no scrap value. The capitalist has been offered $15,000 to sell the machine. If the capitalist's rate of time preference is 5 percent, will the capitalist sell the machine? Does the answer change if the capitalist's rate of time preference is 10 percent?
