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.

The compound interest formula is: 
Where:
A is the amount you will have.
P is the money you are investing.
r: is the interest rate (in decimals)
n: number of times the interest is compounded per year
t: time (in years)
The first thing is converting the rate from percentage to decimal:
Since the interest is compounded every month and a year has 12 months n=12.
Now we can replace the values in our formula:
We can simplify the exponents to get:
Finally, we can use our calculator to get 288463.33
After 18 your balance in your bank account will be $288463.33
