Question 884395: three workers can paint a house in 14 days. assuming that the workers work at the same rate, how many more workers need to be hired to finish painting the house 8 days earlier? Answer by josmiceli(19441) (Show Source):
You can put this solution on YOUR website! three workers can paint a house in 14 days
So, each painter's rate of working is:
( 1/3 house ) / ( 14 days ) =
( 1 house ) / ( 42 days )
------------------------------------
8 days earlier is days
-----------------------------------
A total of 7 painters can work at a rate of: or 1 house in 6 days
-----------------------------------
That means there needs to be
additional painters
