Question 582370
From 2005 to 2007, enrollment at a university decreased by 2%. 
If enrollment in 2007 was 8771 students, what was the enrollment in 2005?
:
Let x = enrollment in 2005
the multiplier for 2% drop is .98
:
This occurred for 2 yrs so we have:
:
x*.98^2 = 8771
x * .9604
x = {{{8771/.9604}}}
x = 9,133 students in 2005
