Answer:
50000
Explanation:
Find the "unit rate" for occupancy:
1500 ft²
------------- = 250 ft²/person
6 people
Now multiply this unit rate by 200 people. "people" drops out, and you are left with
250 ft²
--------------- * 200 people = 50,000 ft²
1 person
Enter 50000. 200 people will need 50000 ft² of housing.
