Question

how is a constant term different from a variable term for an expression that represents a real - world situation?

Explanation:

1. A constant term has a fixed, unchanging numerical value in the real-world expression. It represents a fixed cost, fixed quantity, or unchanging value that does not depend on any changing factor in the scenario.
2. A variable term has a value that changes based on the input/independent variable in the expression. It represents a quantity that scales or shifts based on the changing real-world factor, for example cost per unit multiplied by number of units purchased.

Answer:

A constant term has a fixed value representing an unchanging real-world quantity, while a variable term's value changes based on a varying factor in the real-world scenario.
