Question 878533: if a group of 15 person is required to work for 8 days to complete a project how many days will be taken to complete the project if 5 more people are added

Let r = work rate for one person.
Let t = time in days for the question.
, notice that you do not really need to know the value for rate of one person, because it is a factor to power 1 on both sides of the equation. Solve for t.
