If it takes 4 days for 6 people to finish a job, than how many days does it take 8 people to finish the same job?
----
# of days is inversely related to # of people on the job.
-------
d = k/p
---
Solve for "k" using "it takes 4 days for 6 people to finish a job".
4 = k/6
k = 24
---
Equation for this problem:
d = 24/p
-----
Than how many days does it take 8 people to finish the same job?
d = 24/8
# of days = 3
