Real-World Applications
📋 What it is
Equations model money, distance, recipes, and rates in everyday life.
🗣️ Coach says
Equations are everywhere money or measurement appears: total cost, travel time, doubling a recipe. Spotting the equation inside a real situation turns "maths class" into a tool you actually use.
🧠 Memory hook
Find the unknown in real life, call it x, and the situation becomes an equation you can solve.

What happened to the plant in math class?
It grew square roots!
😲 Whoa!
Every video game runs on equations — an enemy's health, your score, and how fast you fall are all solved thousands of times per second.
✅ Quick check: A taxi costs $3 plus $2 per km. Which equation gives the cost c for k km?
Say your answer out loud first — then reveal.
c = 2k + 3.
The per-km charge multiplies k, and the flat fee is added — a two-step model.
