One engaging real-world application of linear equations for Year 9 students could be calculating the cost of a school trip.

Task: Your school is planning a trip to a local amusement park. The cost of the trip includes the entrance fee and transportation. The entrance fee for each student is \$20, and the transportation cost is \$200 for the entire group.

1. Write a linear equation to represent the total cost (C) of the trip based on the number of students (S) attending the trip.

2. Solve the equation to find the total cost of the trip for different numbers of students attending.

3. Create a table and a graph to represent the relationship between the number of students and the total cost of the trip.

4. Use the equation to calculate the total cost for a specific number of students, such as 30 or 50.

5. Discuss how the equation can be used to predict the total cost for any number of students attending the trip.

Extension: 6. Introduce a variable for the cost of food per student (F). Write a new equation to represent the total cost of the trip, including the cost of food.

1. Solve the new equation for different numbers of students and different food costs.

2. Compare the total cost of the trip with and without the cost of food. Discuss how the cost of food affects the total cost and how it can be minimized.

This task allows students to apply their knowledge of linear equations to a real-world scenario, while also practicing graphing, creating tables, and making predictions. It also encourages critical thinking by introducing the concept of minimizing costs by adjusting variables.

Make this more complex

Sure! Here's a more complex version of the task:

Your school is planning a trip to a popular tourist destination. The cost of the trip includes the entrance fee, transportation, accommodation, and meals. The entrance fee for each student is \$30, the transportation cost is \$500 for the entire group, the accommodation cost is \$100 per night, and the cost of meals per student is \$15 per day.

1. Write a linear equation to represent the total cost (C) of the trip based on the number of students (S) attending the trip.

2. Solve the equation to find the total cost of the trip for different numbers of students attending.

3. Create a table and a graph to represent the relationship between the number of students and the total cost of the trip.

4. Use the equation to calculate the total cost for a specific number of students, such as 40 or 60.

5. Discuss how the equation can be used to predict the total cost for any number of students attending the trip.

Extension:
6. Introduce a variable for the number of nights (N) the group will stay. Write a new equation to represent the total cost of the trip, including the cost of accommodation.

7. Solve the new equation for different numbers of students, different numbers of nights, and different costs of meals.

8. Compare the total cost of the trip with and without the cost of meals. Discuss how the cost of meals affects the total cost and how it can be minimized.

9. Analyze the graph and identify the break-even point, where the cost of the trip is equal to the amount of money collected from the students. Discuss the significance of this point.

This more complex version of the task challenges students to consider additional factors such as accommodation and meals, and how they impact the total cost of the trip. It also introduces the concept of the break-even point, where the cost of the trip is covered by the money collected from the students. This task encourages students to think critically, analyze data, and make predictions based on the linear equations.
