I think we need to use the growth or decay formula.
A = Pe^rt
A = ending amount
P = beginning amount
r = growth or decay rate
t = time or term
e = approximately constant 2.71828
Given:
P = 270,000
r = 2.9% growth
y = ending population
x = time in years
create an equation that models the population of bats, y, after x years.
y = Pe^rx
y = 270,000 * 2.71828^0.029x
A = Pe^rt
