Question 10 3 pts The big battle to defeat the Dark Lord (who shall not be named) caused extensive damage to Hogwarts School of Witchcraft & Wizardry. Unfortunately, school rules forbid using magic to create money. So wizard Harry Potter comes up with a "creative solution". School rules do not block the use of magic on workers, so he creates a spell that makes workers want to work so much that they are willing to pay the employer (the school) for the right to work in the school factory (i.e. the wage rate of labour is negative). Magic also ensures that fixed costs are zero. The school is the only supplier in the world of "genuine" Hogwarts school robes. The world demand curve for robes is given by: P = 2000 - 5Q. where Q is the quantity sold & P is the price per robe in dollars. If the spell causes the marginal cost of output to be -$200 a unit (minus $200 per robe), then the resulting economic profit for the school is: Note: Round your answer to the nearest dollar & do NOT write downany other symbols, so if your answer is $515.63, then this would be entered as 516
