Choice A is the correct answer. Substitute $t = 0$.

1. Substitute: $A(0) = 5000(1.04)^0 = 5000(1) = 5000$.
2. Initial Deposit: The balance at $t=0$ is the initial amount deposited.

💡 Strategic Tip: For $y = ab^x$, when $x=0$, the result is always $a$ (the initial value).

Choice B is incorrect because this is the balance after 1 year, not 0 years. Choice C is incorrect because 1.04 is the growth factor, not a dollar amount. Choice D is incorrect because there is an initial deposit.
