D Question 5 2 pts Joe's Taco Hut can purchase a delivery truck for $20,000, for which he will take out a loan from the bank. He estimates it will generate a net income (after taxes, maintenance, and operating costs) of $4,000 per year. His other option is to go to work for someone else earning net income of $3,000 per year. Assume that Joe can resell the truck for the entire purchase price of $20,000.
