Concepts

A student is solving a word problem and writes the following as their
first step:

"Let $x$ be the amount."

Which concern is most important to raise about this variable definition?

$x$ should be a letter other than $x$ to avoid confusion.

The definition does not state the units or specify what quantity $x$
measures, making the answer uninterpretable.

The student should define two variables, not one.

Variable definitions should come after the equation is written.
