Answer
$127.3$ million.
Work Step by Step
The mathematical model for exponential growth or decay is given by
$ f(t)= A_{0}e^{kt}$ or $ A= A_{0}e^{kt}$.
If $ k \gt 0$, the function models the amount of a growing entity.
$ A_{0}$ is the original amount, or size, of the growing entity at time t = 0,
$ A $ is the amount at time $ t $, and $ k $ is a constant representing the growth rate.
If k $ \lt $ 0, the function models the amount of a decaying entity
----
In 2010,
the time passed, t=0 (t = years after 2010), and $ A_{0}$ for the given model $\quad A=127.3e^{-0.006t}$
equals $127.3$ million.
