a. Think about how many people in New York City want to drive during rush hour, during a non-rush-hour hour during the day (for ease, think of this as "midday"), and during an hour in the middle of the night. Show the demand curve for the number of vehicle trips people want to take during an hour in New York City at each of these three times of day and briefly explain your choices about how to represent these curves. Also show the supply curve for vehicle trips during an hour. Assume the supply curve does not shift with the time of day - in other words, there will be just one supply curve in your graph
