Question 662106
Let b = Bailey's rate in houses/day
Then Andrew's rate = 6b houses/day
Working together, it takes them 5 days to paint the house, so their combined rate is 1/5 houses/day:
b + 6b = 1/5
7b = 1/5 
b = 1/35 house/day
So Bailey would take 35 days to paint the house, Andrew would take 35/6 = 5 5/6 days
