1.What is the difference between economic profit and producer surplus?

2.Suppose you won a free ticket to see an Eric Clapton concert ticket. You can't resell it. Bob Dylan is performing on the same night and his concert is the only other activity you are considering. A Dylan ticket costs $30 and on any given day you would be willing to pay as much as $45 to see him perform. (In other words, if Dylan ticket is sold for more than $45, you would pass on the opportunity to see him even if you had nothing else to do). There is no other cost of seeing either performer. What is your opportunity cost of attending the Clapton concert?
