So if you wanted to bill 100k in labor per year you would be at $50/hr at 2000hr/year or $66 at 1500hr/year. The real world is somewhere between these two scenarios for most small one man shops. My point is everyone is always thinking billable hours. Non billable hours eat into the hourly rate tremendously.
Then lower the heat to 350Â°F (175Â°C) and bake for and additional 10-30 minutes more until the juices run clear (not pink) when poked with a sharp knife or the internal temperature of the chicken breasts is 165Â°F (74Â°C) and of the thighs is 170Â°F (77Â°C).
To cook a two and a half pound roast, preheat the oven to 325  degrees and roast for 1 1/2 to 2 hours.
