Situasi Berbasis Masalah

1. Imagine you're planning a road trip and need to calculate how many kilometers you can travel on a full tank of petrol. For this, you need to compare two linear equations that represent fuel consumption at different speeds and determine where they meet.

2. Consider you have a challenge from a math competition: 'Given the price of a combo of a burger and a soda and the individual prices of each, come up with and compare two equations that represent different combinations of burgers and sodas costing the same amount.' How would you solve this using linear equations?

Kontekstualisasi

Linear equations are critical tools in our daily lives, not just in mathematics but also in various practical situations. For example, when calculating monthly expenses, predicting future costs, or even in fields like engineering to design structures and technology. The ability to compare linear equations helps in making informed decisions based on data and mathematical models.

• Provide each group with equations describing different types of load support along a bridge.

• Students will compare the equations to see where the load is maximum and where the structure requires reinforcement.

• Using materials like ice cream sticks and glue, students will build a model bridge that aligns with the given equations.

• In the end, each group will present their bridge and explain how their construction decisions were based on the provided equations.

Kegiatan 3 - The Great Fixed Price Challenge

> Durasi: (60 - 70 minutes)

- Tujuan: Utilize linear equations to optimize pricing and grasp basic economic concepts.

- Deskripsi: In this scenario, students, divided into groups, will take on the roles of café managers striving to optimize their prices. They will compare various combinations of products (coffee, milk, sugar) using linear equations to figure out when costs are the same, aiding in pricing decisions.

- Instruksi:

• Divide the class into groups of up to 5 students, with each group representing a different café.

• Provide each group with distinct equations representing the costs of different product combinations.

• Students will use the equations to identify the point at which costs are equal, allowing them to set competitive prices for their café.

• Each group will present their pricing strategy and explain how the equations assisted in their decision-making.

• Conclude with a discussion about the diverse pricing strategies and methods used by the groups.
