Answer
There will be around 333 bison after 10 years.
Work Step by Step
This involves exponential growth as the population will increase by 2.5 percent annually.
RECALL:
Exponential growth is represented by the formula
$y=C(1+r)^x$
where
C = initial/original amount
r = growth rate
x = number of time intervals
The given situation has:
C = 260
r = $2.5\%$ per year
x = 10 years
Substitute these values into the given formula above to have:
$y=260(1+2.5\%)^{10}
\\y=260(1+0.025)^{10}
\\y260(1.025^{10})
\\y \approx 333$
