A certain species of endangered frog has a population of 120,000. Due to habitat loss, the population is decreasing by $5%$ every decade. Which equation models the population of the frog species, $P (d)$ , after $d$ decades?

A.

$P (d) = 120000 (0.05)^{d}$

B.

$P (d) = 120000 (0.95)^{d}$

C.

$P (d) = 5 (120000)^{d}$

D.

$P (d) = 0.95 (120000)^{d}$
