A symbol used to represent a quantity that can change is called a what?

Explanation:
Variables are symbols used to stand for numbers that can change. They let us model quantities that aren’t fixed yet or can vary in different situations. For example, x might represent the number of apples you have, and as you add or remove apples, x changes. An equation is a statement that two expressions are equal. A constant is a fixed number that never changes. A fraction shows a part of a whole. So a symbol that represents a quantity that can change is a variable.
