The bill ($15,000) for some consulting work provided for your company just arrived. The consultant worked with 3 of the department managers to identify cost saving opportunities. You are the manager of Department A. The manager of Department B has suggested that the bill be split evenly between the 3 departments. The Department C manager suggests that Department A should pay the entire bill since most of the work was done for Department A. The time spent by the consultant was:

Dept. A 60%

Dept. B 30%

Dept. C 10%

Write a memo to the other department managers with your recommendation of how the bill should be split up.
