Every day, 500 airplanes in San Francisco incur an additional 30 minutes of airport delays when flying into or out of the airport. In Chicago, the delays amount to 15 minutes for 1,400 airplanes. If the price of time is $20/hour in San Francisco and $15/hour in Chicago, which airport incurs the largest opportunity cost?

Chicago makes $5250 because 15/4=3.75 (divided by 4 because 15 mins is a quarter of an hour) and 3.75x1400=5250
Whereas 20/2=10 (divided by 2 because 30 mins is half an hour) 500x10=5000

So Chicago makes $5250
San Francisco makes $5000
