I bought a used car at 50%-off sale. I didn't drive it much, so I sold it for 50% more than I paid for it. When I missed having "wheels," I bought the car back at 50% less than I sold it for. Soon gas was costing too much, so I sold the car again for 50% more than I paid for it the second time. Now I am confused, so I hope you can help. What percent of my original investment did I make or lose?
