Question 1 A study of the price elasticities of products sold in supermarkets contained the following data. PRODUCT PRICE ELASTICITY OF DEMAND Soft Drinks 4.76 Canned soup 1.68 Cheese 0.77 Toothpaste 0.42 (a) What is the meaning of the concept price elasticity of demand? Applying this to the products in the table above, categorise the products into those with elastic and inelastic demand. (2 marks) Price elasticity of demand (PED) is the percentage change in the quantity demanded of a good or services as a result of a 1% change in the price of the good or service. If PED Is greater than 1 demand is elastic, if PED is less than 1 but greater than zero then demand is inelastic. If PED is equal to zero demand is perfectly inelastic and if PED is infinity then demand is perfectly elastic. (1 mark for the above definition and magnitudes of PED as they facilitate categorisation) (1 mark for the categorisation of the goods) (b) Discuss why the demand of each product is elastic or inelastic. (5 marks) Product Nature of Elasticity Reason Soft Drinks Elastic Many substitutes (1 mark) Canned soup Elastic Many substitutes (1 mark) Cheese Inelastic Few substitutes (1 mark) Toothpaste Inelastic Necessity Few substitutes (2 marks) (c) Critically evaluate the following statement: “Increasing the price of soft drinks and toothpaste would result in total revenue earned from each of the products. (3 marks) Increase in price does not necessarily transalte to an inctease in total revenue as this depends how price elastic are the products. For price elstaic products an increase in price reulsts in a decraese in quantity that cuaes total revenue to decreae. For price inelastic product, an increase in price would result in an increase in revenue due to the fact that there woild be a slight derease in quantity sold, not enough to cause revenue to fall. Applying the above it means the incerase in price would cause totral revenue from soft drimks to decrease while that of toothpaste to increase.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
