I am an entrepreneur and I currently own solar-powered equipment (truck and mower). It take me about two hours to cut a lawn, and I cut 1,000 lawns per year. My equipment can be sold for $20,000 at any time. I could also earn $12/hour as a pedicurist. The interest rate is 10 percent. I need to know total opportunity cost, opportunity cost of each lawn, current output level, marginal cost and average cost
