The amount of money in a savings account after [tex]$t$[/tex] years is represented by the function [tex]$f(t) = 3600(1.035)^t$[/tex]. What does the value 3600 represent in this situation?

A. The amount of money in the savings account decreases by \$3600 each year.
B. The initial amount in the account is \$3600.
C. The amount of money in the savings account increases by \$3600 each year.
D. The amount of money in the savings account is 3600 times the amount of the previous year.

Answer :

We are given the function

$$
f(t) = 3600(1.035)^t,
$$

which represents the amount of money in a savings account after $t$ years. Here’s a step-by-step explanation:

1. In an exponential function of the form

$$
f(t) = A(1+r)^t,
$$

the constant $A$ is the initial amount in the account. This is because when $t = 0$, we have

$$
f(0) = A(1+r)^0 = A \times 1 = A.
$$

2. Substituting $t = 0$ in the given function yields:

$$
f(0) = 3600(1.035)^0 = 3600 \times 1 = 3600.
$$

3. This calculation shows that the account starts with $\$3600$. It is not an amount that is added each year or a decrease, but rather the amount present at the very beginning.

4. Therefore, the value $3600$ represents the initial amount in the savings account.

Thus, the correct interpretation is:

$$\textbf{The initial amount in the account is } \$3600.$$
