Answer:
It is a growth rate of 86%.
Step-by-step explanation:
Hi, to answer this question we have to analyze the exponential function:
A = P (1 + r) t
Where:
p = original population
r = change rate (decimal form)
t= time (x)
A = population after t years
Replacing with the values given:
y = 270(1.86)^x
Since the term 1.86 is equal to 1+ 0.86, it is a exponential growth because the rate is positive. (r =0.86)
In percentage form: 0.86 x 100 =86%
