b. The university, in order to prevent the shortage issue, is changing from selling parking permits to charging a daily parking fee. Suppose parking spaces were allocated at Arturo's school using the market mechanism. In this case, students would have to pay $ each day to park. c. As his school gets larger, the demand for parking increases to Q_D=12,000-500P. If Arturo's university wanted to keep the market price (the price of daily parking) the same, it would have to provide more parking spaces.
