To solve this problem, you must follow the proccedure below:
1. First, you must calculate the Constant of proportionality "k".
2. The problem says that the number of days needed to remodel a house varies inversely as the number of people working on the job. Then:
Number of days=K/Number of people
K=(Number of days)(Number of people)
18 weeks=135 days
K=135x4
K=540
3. Now, you have:
Number of days=540/Number of people
8 weeks=60 days
Number of people=540/60
Number of people=9
How many people are needed?
The answer is: 9
