Celtic Spirit Brewing is a company specializing in seasonal beverages. It currently has two divisions: the Lager Division and the Bottling Division. The Lager Division sells each keg of its limited-edition green lager to external customers for $300 each. Each keg has fixed costs of $25 per unit and variable costs of $125 per unit. Management at Celtic has requested that the Lager Division transfer 500 kegs to the Bottling Division at a price of $250 per keg. Lager Division is already operating at full capacity and would have to sacrifice external sales of 300 kegs to fulfill this internal request. The Lager division can avoid $30 of variable cost per keg due to fewer shipping and handling costs when selling to the Bottling Division. What is the minimum transfer price per keg that the Lager Division should accept? (Do not round intermediate calculations. Round your final answer to the nearest whole dollar.)
