ANSWER
[tex]y=25,000\cdot0.95^t[/tex]
EXPLANATION
Exponential decay is modeled by the equation,
[tex]y=a\cdot(1-r)^t[/tex]
Where a is the initial value, in this case, a = $25,000, and r is the decay - or decrease, rate. In this problem, r = 0.05.
The equation is,
[tex]y=25,000(1-0.05)^t[/tex]
Solve the subtraction to write it in the asked form,
[tex]y=25,000\cdot0.95^t[/tex]
