Understanding Fixed and Variable Expenses

The video tutorial introduces the concept of fixed and variable expenses, focusing on a fourth-grade math standard from Texas. It uses a problem from the 2022 STAR test to illustrate these concepts. Fixed expenses are defined as costs that remain stable, like rent and cable TV, while variable expenses change based on usage, such as water and electricity bills. The tutorial provides examples and explanations to help students differentiate between these two types of expenses.
