rate of change of what?

rate of change of spending per year??

from 2011 to 2015
= change in spending/change in time
= (252655.5 - 221155.9)/(2015-2011)
= ....

oh I forgot to include that yes, rate of change of spending per year. Thank you

The formula for calculating the rate of change is:

Rate of change = (Final value - Initial value) / (Change in time)

To find the rate of change of Texas spending from 2011 to 2015, we need to calculate the difference in spending and the difference in time.

The difference in spending is:
Final value - Initial value = 252,655.5 - 221,155.9 = 31,499.6

The difference in time is:
Change in time = 2015 - 2011 = 4 years

Now, we can use the formula to find the rate of change:
Rate of change = (31,499.6) / (4) = 7,874.9

Therefore, the rate of change of Texas spending from 2011 to 2015 is approximately 7,874.9.
