When Ms. Lucinda Sanchez graduated with honors from the American Trucking Academy, her father, Billy Sanchez gifted her with a $150,000 tractor-trailer rig. At a Truck Stop in Hondo, Texas Lucinda was boasting to some fellow truckers that her revenues were typically $85,000 per month, while her operating costs (fuel, maintenance, insurance and depreciation) amounted to $45,000 /month, motel and food costs another $15,000 on the road. Tractor-trailer rigs identical to Burton's rig rent for $17,000 per month with similar operating costs.

1. How much are Lucinda's monthly explicit costs? How much are her monthly costs per month?
2. What is the dollar amount of the opportunity cost of the resources used by Lucinda each month?
3. Lucinda is proud of the fact that she is generating a net cash flow of $25,000 per month, since she would be earning only $12,000 per month if she were working for a trucking firm. What advice would you give Ms. Lucinda Sanchez? Why?
