## Unscramble the Blue Letters

And so, the question is, what does that cost us? That ineietoctsrn I loekod at had about 3,000 cars per day in each dotiriecn, and so that's two ounces of gas to aretlcecae out of. That's five cents each, and times 3,000 cars per day, that's $51,000 per year. That's just the gasoline cost. There is also pltouoiln, wear on the car, and time. What's that time worth? Well, at 10 seconds per 3,000 cars, that's 8.3 hours per day. The average wage in the U.S. is $20 an hour. That is 60,000 per year. Add that together with the gas, and it's $112,000 per year, just for that sign in each direction.
