It takes 5 people 6 days to paint a house, working 8 hour shifts.
a) how long would it take 4 people to complete the same job?
b) how many people would be needed to complete the same job in less than 4 days?
~~~~~~~~~~~~~~~~

The entire job is 5*6 = 30 working days.



(a)  With 8 hours shift, 4 workers will complete the job in  30%2F4 = 7 1%2F2  working days = 7.5 working days = 7 days and 4 hours.


(b)  30%2F4 = 7.5;  therefore,  at least 8 workers should be employed to complete the job in less than 4 days.
