Absolute Value Equations and Tolerances

The video tutorial explains how to create and solve absolute value equations from word problems. It outlines the steps to identify variables, determine tolerance, and write equations. Three examples are provided: determining the weight range of sugar bags, finding the grade range in a class, and modeling the range of money in a wallet. Each example demonstrates how to set up and solve the equations, as well as interpret the solutions.
