Answer:

$f(t) = 13,500(0.89)^t$

Step-by-step explanation:

The formula for the exponential function is given as $f(t) = a(b)^t$

Where,

base value = a = $13,500

b = 1 - % decrease = 1 - 11% = 1 - 0.11

b = 0.89

Substitute the values of a and b into the exponential function, $f(t) = a(b)^t$ , respectively.

Thus:

$f(t) = 13,500(0.89)^t$
