Answer: If the producers of the show charge $497.50 for a premium seat, the scalpers will charge (a) $1200 , which is (b) $702.50 more than the price listed at the theater's box office.
Step-by-step explanation: The producers are charging $497.25 for 400 seats as given by the supply curve. The scalpers will therefore charge a price which is given by the demand curve for 400 seats. Thus, the scalpers will charge $1200 for Broadway premium tickets.
The difference will therefore be= $1200 -$497.50 = $702.50
