It takes a 160 work days to build a house. this means that one person could build the house and 160 days but two people could build it the house and 80 days. create a table to figure out a relationship between the number of people working and days to completion.

days = → n is number of people

1 person → 160 days

2 people → 80 days →

4 people → 40 days →

8 people → 20 days →

let n be the number of people, then

days =

b
