The average change in the tuition in the school is $1748.30 per year
<h3>How to find the average rate of change</h3>The formula would be
y2 -y1 / x2 - x1
The value for y1 = 19890
y2 = 30380
x2 = 2011
x1 = 2005
We would have to put these values in the formula that we have above such that we would be having:
30380 - 19890 / 2011 - 2005
10490 / 6
= $1748.30
Hence we would say that the average rate of change is $1748.30 per year.
