In the SQA Business curriculum at Year 9 level, learners are expected to connect business concepts with other subjects such as Maths, English, Geography and ICT. Interdisciplinary questions test your ability to apply knowledge in realistic scenarios, just like in the modern workplace. This article provides targeted training for common cross-subject question types, with step-by-step examples and model answers.
在Year 9阶段的SQA商务课程中，学生需要将商务概念与数学、英语、地理和信息通信技术等其他学科联系起来。跨学科问题考查你在真实情境中应用知识的能力，就像在现代职场中一样。本文针对常见的跨学科题型提供专项训练，包含逐步示例和参考解答。
1. Integrating Maths and Business: Profit and Break-even | 数学与商务融合：利润与盈亏平衡
Mathematical skills are essential for any business owner. You must be able to calculate total costs, revenue and profit, and determine the break-even point. In SQA exams, you may be given a scenario with fixed costs, variable costs per unit and selling price, and asked to perform calculations.
数学技能对任何企业主都至关重要。你必须能够计算总成本、收入和利润，并确定盈亏平衡点。在SQA考试中，你可能会获得包含固定成本、单位可变成本和售价的情境，并被要求进行计算。
Example Question: A small bakery has monthly fixed costs of £2,400. Each loaf of bread costs £0.80 in variable costs and is sold for £2.20. Calculate the break-even point in units and the profit if 1,500 loaves are sold.
例题：一家小面包店每月固定成本为2400英镑。每条面包的可变成本为0.80英镑，售价为2.20英镑。计算盈亏平衡点（单位：条）以及销售1500条面包时的利润。
First, identify the contribution per unit: Selling price − Variable cost = £2.20 − £0.80 = £1.40. Then, break-even point (units) = Fixed costs ÷ Contribution per unit = £2,400 ÷ £1.40 = 1,714.3, so 1,715 loaves (round up since you cannot sell part of a loaf).
首先，确定单位贡献：售价 − 可变成本 = 2.20 − 0.80 = 1.40英镑。然后，盈亏
