This activity Food develops students’ ability to calculate and interpret income elasticity of demand through four food-business scenarios, including changes in forecast sales volumes.

In Food for Thought, students complete four contextual calculations on income elasticity of demand. They calculate YED from changes in income and quantity demanded for breakfast wraps and value ready meals, then use given elasticity figures to forecast pizza sales after a rise in customer income. Finally, they interpret an income index chart and estimate demand for premium lobster dishes in 2024 and 2025. The worksheet practises percentage changes, elasticity formulae, positive and negative YED, and demand forecasting skills.
