Comparing Money: Shawn and Maria's Savings Challenge

In this lesson, we explore a problem involving Shawn and Maria's earnings. Shawn starts with $12 and earns an additional $5, while Maria has $17 and also earns $6. We'll determine whether they have the same total amount of money after their earnings. By solving the equations for each person's total amount, we find Shawn has $23 and Maria has $23 as well. This problem highlights the importance of organizing information and checking work using models to validate results.
