Question 1 The change in attendance for a school for 2010, 2011, 2012, & 2013 were a 5% increase between 2010 & 2011, 15% between 2011 & 2012, and a 30% decrease between 2012 & 2013. What is the change in attendance between 2010 & 2013?

-- Answer -- 84.5% or 15.5% decrease

x = attendance in 2010

Change in attendance = x (1 + 5%)(1 + 15%)(1 - 30%) = x * 84.525%
