A student sees this description: "A savings account earns 3% interest each year."
The student classifies it as a constant rate situation and writes $f(t) = 0.03t + b$ .
What error did the student make?

The student used the wrong variable name.

The student confused constant percent rate (exponential) with constant rate (linear).

The student forgot to include the initial value $b$ .

The student should have written $f(t) = 3t + b$ instead.
