Add up all the beds. Then for each department, you use a fraction based on number of beds in that department/total numbers of beds. Multiply that fraction times the total $400. Ex: Dept 1 has 6 beds. 6/81 * 400 = 2400/81 which is approx. $29.63. Do the same thing with each department. When you add the amounts each dept. is charged, the answer should be approximately $400.
If you still have a question, please let me know.
