Sharpen your argument
A fictional firm can accept an order for HK$5,000. Extra materials cost HK$2,000 and extra labour HK$1,000. A HK$800 allocated rent charge is unchanged. There is spare capacity. What is the incremental contribution? Choose the strongest starting point.
Incremental revenue is HK$5,000; incremental costs are HK$3,000.
This supports acceptance on the stated financial assumptions, but check effects on quality, customers and future pricing. All figures are hypothetical.
The weaker choice: Keep sunk costs separate from costs that change with a decision. A correct total is not useful if it answers the wrong managerial question. watch this!

A weekly rhythm, two checklists, and the traps to avoid
The course rewards consistency over cramming, and practice over re-reading. Here is the loop that works, then what to have nailed before each exam.
The weekly loop
Before the mid-semester checklist
- Check the current source version and task brief.
- Explain the main concept without copying the wording.
Before the final heaviest topics
- Review your assumptions and evidence.
- Check the current submission and permitted-use rules.
The mistakes that cost marks
Skipping the assumptions. Keep sunk costs separate from costs that change with a decision. A correct total is not useful if it answers the wrong managerial question.
