Answer:

Percentage increase every year is 9%

Step-by-step explanation:

If we have a function of the form


y=(1+a)^t

then a* 100% is the percent increase.

Now, the function


y=(1.09)^t

can be rewritten as


y=(1.00+0.09)^t

meaning a = 0.09; therefore, the percent increase is


0.09\cdot100\%
=9\%^{}

which is our answer!
