... P = 55 - (2) (10) = $35. Profits are equal to total revenue minus total cost: π = (35) (10) - (100 - (5) (10) + 10 2 ) = $200. Consumer surplus is equal to one-half times the profit-maximizing ... MC to determine the profit-maximizing quantity: 5 = 50Q -1 /2 , or Q = 100 . Substituting Q = 100 into the demand function to determine price: P = (100 ) (100 -1 /2 ) =...
