Inequality Word Problems Challenge

The video tutorial covers solving inequality word problems, focusing on two examples. The first example involves Jack's family planning a trip to Disney World with a budget constraint, requiring the setup and solution of an inequality. The second example involves Keith's savings account, where he withdraws a fixed amount weekly, and the goal is to determine how many weeks he can continue this while maintaining a minimum balance. The tutorial emphasizes setting up inequalities, solving them, and understanding the implications of the solutions.
