Answer:
Decrease of 63.5%.
Step-by-step explanation:
Exponential function:
An exponential function has the following format:
[tex]y = y(0)(1+r)^{x}[/tex]
In which y(0) is the initial value and r is the rate of change, as a decimal. If r is positive, it is a increase. If it is negative, it is a decrease.
In this question:
We have that:
[tex]y = 3100(0.365)^x[/tex]
So
[tex]1 - r = 0.365[/tex]
[tex]r = 0.365 - 1 = -0.635[/tex]
So a decrease of 63.5%.
