School Canteen Reform Under a Tight Budget
A Year 9 student council at a 900-student secondary college wants to change the canteen menu. The canteen currently sells hot chips, sausage rolls, soft drinks and white-bread sandwiches. Survey data shows 62% of students buy lunch at the canteen at least three days a week, and the canteen makes a $4,200 monthly profit that funds the sports program. The council proposes replacing chips and soft drinks with a salad bar, fruit cups and flavoured milk. The canteen manager warns that salad ingredients cost more per serve, spoil quickly, and that students may simply walk to the nearby shops. The principal will only approve changes that keep the canteen profitable within one term.
1. Explain why the student council's proposal cannot be judged using nutrition knowledge alone, and identify the competing considerations the principal must weigh.

Nutrition knowledge tells us that the current menu is high in energy, saturated fat, sodium and added sugar, and low in fibre and fresh vegetables, so the proposal would improve the nutritional profile of foods available. But whether the change should be approved is a food-systems and decision-making question, not a purely nutritional one.
The principal must weigh several competing considerations:
- Financial viability: the $4,200 monthly profit supports sport. Higher-cost salad ingredients, spoilage losses and possible lower sales volume could shrink or erase that profit, so the one-term profitability condition is a real constraint.
- Student acceptance and behaviour: students are consumers with preferences; if the healthier option is rejected, they may leave the school grounds and buy elsewhere, which removes both the revenue and any nutritional benefit.
- Practical food handling: fresh produce has a short shelf life and needs refrigeration and preparation labour, which the canteen may not have.
- Equity: a more expensive salad bar may price out students who rely on the canteen for an affordable lunch.
A defensible judgement is that the proposal should be trialled and monitored (sales data, waste, uptake) rather than accepted or rejected outright, because nutrition goals and business goals are both legitimate and can conflict.
2. The manager claims students 'may simply walk to the nearby shops'. Explain how this claim should be tested before the principal makes a decision.

The claim is a prediction about consumer behaviour, so it should be treated as a hypothesis to be tested, not a fact.
Ways to test it:
- Check current data: if 62% already buy at the canteen three or more days a week, find out why - price, convenience, time, or limited alternatives. Exit surveys can reveal what would make students leave.
- Run a limited trial: offer the new items alongside a reduced range of old ones for several weeks and record sales, waste and the number of students leaving the grounds at lunch.
- Compare price points: test whether a salad at a similar price to chips retains sales, since price is often the deciding factor for students.
- Ask about the walk: the distance to shops, time available at lunch and supervision rules all affect whether leaving is realistic.
If the trial shows sales hold up, the manager's warning is weakened; if sales fall and students leave, it is supported. The decision should rest on this evidence rather than on the manager's assertion.
