#### Unscramble the Blue Letters

And so, the question is, what does that cost us? That irnteocsetin I lokeod at had about 3,000 cars per day in each direction, and so that's two oecuns of gas to accelerate 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 pollution, wear on the car, and time. What's that time wtroh? 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 doreiticn.

#### Original Text

And so, the question is, what does that cost us? That intersection I looked at had about 3,000 cars per day in each direction, and so that's two ounces of gas to accelerate 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 pollution, 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.
