Answer:
8
Step-by-step explanation:
We can create a equation to find out.
since we are finding a number where when multiplied by 1.25(this is the decimal form of the percentage) gives us 25, we know that the number we are finding is less than 25. here is the equation.
1.25(x)=25
divide both sides by 1.25 to get "x" alone.
x= 20
When x = -6 the denominator = 0
There is a hole in the graph at (-6,0)
The formula for exponential decay is
![y=a(1-r)^{x}](https://tex.z-dn.net/?f=y%3Da%281-r%29%5E%7Bx%7D%20)
where a is the initial value (28750)
r is the rate of decrease (0.12)
x is the time, in this case in years (6 . 2018-2012 = 6 years)
![y=28750(1-0.12)^{6}](https://tex.z-dn.net/?f=y%3D28750%281-0.12%29%5E%7B6%7D%20)
