Crystal will be the first to get to Boston on the northwestern train going 32.5 mph. Even though she has an extra 4.9 miles to travel because she left at 9:22am while descending down a 92 foot hill and x = 32 over q she still wins the race.
^Crystal wont be able to make her flight to Boston anymore. Jessica and Maria won't either. All because of that extra dollar which set off a chain reaction similar to the motion picture film How High. "Got yay?" "Got a dollar?"
One US Dollar is worth 1.154890 of a Doller. Since the hotel was charging in dollers and not dollars, you need to factor in the exchange rate. 29 x 1.154890 = 30. That's where the extra doller went.
