Calculate the price, in cents per gram, for each packet of apples. Identify the option that gives the best value for money. Explain why prices do not always increase proportionally as quantity increases.

Step 1: Answer 3.1 by calculating the price per gram for each packet. To calculate the price in cents per gram, first convert kilograms to grams (1 kg = 1000 g) and Rands to cents (1 R = 100 cents). • 1 kg packet: Quantity: 1 kg = 1000 g Price: R25 = 25 × 100 cents = 2500 cents Price per gram: 2500 cents1000 g = 2.5 cents/g • 2 kg packet: Quantity: 2 kg = 2000 g Price: R44 = 44 × 100 cents = 4400 cents Price per gram: 4400 cents2000 g = 2.2 cents/g • 5 kg packet: Quantity: 5 kg = 5000 g Price: R100 = 100 × 100 cents = 10000 cents Price per gram: 10000 cents5000 g = 2 cents/g The prices per gram are: • 1 kg packet: 2.5 cents/g • 2 kg packet: 2.2 cents/g • 5 kg packet: 2 cents/g Step 2: Answer 3.2 by identifying the option that gives the best value for money. The best value for money is the option with the lowest price per gram. Comparing the calculated prices: • 1 kg packet: 2.5 cents/g • 2 kg packet: 2.2 cents/g • 5 kg packet: 2 cents/g The 5 kg packet has the lowest price per gram. The option that gives the best value for money is the 5 kg packet. Step 3: Answer 3.3 by explaining why prices do not always increase proportionally as quantity increases. Prices do not always increase proportionally with quantity due to economies of scale and marketing strategies. Supermarkets often offer bulk discounts for larger quantities because the cost of packaging, handling, and transportation per unit decreases. This allows them to sell larger packets at a lower price per unit (e.g., per gram) while still maintaining profitability and encouraging customers to buy more. Step 4: Address Question 4. The provided image for Question 4 (Jabu's savings) only contains the introductory text and an image. It does not include any specific sub-questions (e.g., 4.1, 4.2, 4.3, 4.4) or a table to complete. Therefore, Question 4 cannot be answered without further information.
