In the Fall of 2010, Colorado University announced tentative increases in tuition for the following years:
2011 9.5%
2012 9%
2013 9%
2014 9%
2015 9%
The reporter stated that it was nearly a 50% increase in tuition over the next five years. What would the actual increase
in tuition be from 2010 to 2015?
Solution to the Problem:
The answer is 54.57%.
Let x = tuition at C.U. in 2010.
Then 1.095x = tuition in 2011.
Then 1.09 times 1.095x = 1.19355x = tuition in 2012.
Then 1.30096x = tuition in 2013.
Then 1.418050x = tuition in 2014.
Then 1.54568x = tuition in 2015.
