 · Answer

2	one-half of an hour=0.50 hours=30 minutes
	18 minutes=18/60=0.30 hours

	Ratio
	30:18	or	0.50:0.30

3	Ratio=120:80:20
	To simplify divide the numbers by 20
	Ratio=120/20:80/20:20/20=6:4:1

4	Rent absorbed by Department B=Total rental(floor space of department B/Total floor space for all departments)=38225[120/(310+120+475)]=38225*(120/905)=$ 5068.508

5	Cost of operating absorbed by each department=Cost of operating*(Floor space of the department/Total floor space of all departments)
	Total floor space of all departments=1100+660+880+440=3080
	Department A=24000*(1100/3080)=$ 8571.429
	Department B=24000*(660/3080)=$ 5142.857
	Department C=24000*(880/3080)=$ 6857.143
	Department C=24000*(440/3080)=$ 3428.571
