Suppose a company has three profit centers with the following information: Corporate costs are allocated to the divisions as follows: Headquarters Rent Expense is allocated based on square feet occupied Corporate Marketing Expense is allocated based on sales Human Resources Expense is allocated based on headcount Allocate the following costs according to the conventions shown above. Round percentages to the nearest tenth of a percent (for example, 33.5% ) and round answers to the nearest whole dollar Finally, figure total amount allocated to each division
