10 people paint a building in 3 days. The owner would like the next building to be painted in 2 days. Assuming new people work at the same rate as the first 10, how many more people must be hired?
10 people = 3 days
1 person = 30 days
30 people= 1 day
? People = 2 days
people= 30 /2days
People = 15 people will complete the building in 2 days.
15-10= 5.
Therefore 5 people will be added to complete the painting in 2 days.
Answer is 5 people
