Answer: a. total labor hours incurred in the divisions
Step-by-step explanation:
The best way to allocate payroll costs would be to apportion it by hour. The labor in the various departments should work by the hour and then the total amount of hours worked in the division will then be used as the base for payroll because it would show how much people in that division worked and how much they need to be compensated for doing so.
For instance, assume the total payroll cost is $1,000,000 and Division A worked 2,000 hours, Division B worked 4,000 hours and Division C worked 4,000 hours. The payroll would be apportioned as follows:
Division A = 2,000 / (2,000 + 4,000 + 4,000) * 1,000,000 = $200,000
Division B = 4,000 / (2,000 + 4,000 + 4,000) * 1,000,000 = $400,000
Division A = 4,000 / (2,000 + 4,000 + 4,000) * 1,000,000 = $400,000
