Question

Describe how to use a verbal model to solve a problem.

Short answer

A verbal model involves identifying the problem, translating it into words (variables, relationships, conditions), and solving the problem using this model. It can be revised and refined as needed.

Step-by-step solution

Identify the Problem Statement

Read the problem carefully and identify the problem statement. Understand what question is being asked. Identify the information provided and what you need to find out.

Translate into a Verbal Model

Translate the problem statement into a verbal model. This includes identifying and naming the variables, the unknowns, the relationships between them, and the conditions or constraints. Use words to describe these.

Solve Using the Verbal Model

Use your verbal model to derive a solution. This may involve creating a plan, selecting a strategy (e.g. compare, add, subtract etc.), carrying out the plan, testing the model, and refining the model as needed. Remember that it's okay if your initial model doesn't work perfectly; adjust as necessary.
