A mural of Michael Jackson takes 56 days to complete by seven painters. 28 volunteers join the team after the first six days. How many more days are required before the painting is completed?
Ooops....I didn't see the volunteers joined after 6 days recalculating!
After adding 28 painters they now have 35 painters to do what would take 7 painters 50 days to complete
7/ 35 x 50 = 10 days to complete
