✏️ Part 2: Short Answers — Apply & Explain

5. Practical substitution: A café charges $2 per sausage roll plus a $3 flat fee. Write the cost C for n sausage rolls and calculate C when n = 4.

6. Formulate an expression: Sam starts with $10 and earns $y each week. Write an expression for Sam's total money after w weeks.

7. Table and prediction: The rule is y = −3x + 12. Complete the values for x = 1, 2, 3 and then find x when y = 0. Show working.

8. Geometry to algebra: The width of a rectangular garden is 3 m and the length is L metres. Write an expression for the perimeter P in terms of L.

🚀 Extension & Reflection

9. Extension (advanced): From the table below, determine the function rule (linear) and state y when x = 5.

x: 1, 2, 3

y: 3, 5, 7

10. Reflection: Briefly describe one strategy you used for solving questions today and one area you would like help with. (2–3 sentences)

Differentiation & teacher notes: Offer one-on-one support or simplified wording for students who need it. Provide dyslexia-friendly printing (Arial/OpenDyslexic, increased spacing, colour-coding for variables). Extension tasks: present work to peers or solve the extension problem on the board.
