Understanding Inequalities and Functions

Mr. Woolley introduces inequalities, explaining their use in solving real-world problems. The video covers examples like saving for a tablet, budgeting for a fair, and calculating baggage weight. Students learn to write and solve inequalities, apply them to practical scenarios, and understand their significance in decision-making.
