INVESTIGATIVE QUESTION: COMPARING PRICES 1.1 The grade 10 learners of Loago Secondary are conducting an investigation on prices of some grocery items. They decided to have a look at the prices of concentrate juice. The mixing proportion of the juice (concentrate: water) is 1:5. Table 1 below shows the prizes and sizes. TABLE 1: PRICES AND SIZES OF JUICE Use the table above to answer the questions that follow: 1.1.1 How much does the 1,25l-bottle of juice cost? 1.1.2 What is the mixing proportion for the 1,5l-bottel? 1.1.3 The learners decided to buy three 1,5 litres of juice (a) Calculate the cost of the juice? (b) How much juice would be made? 1.1.4 Calculate the cost per litre of the 1,25l-bottle. 1.1.5 Calculate which one of the three had the best value for money, regarding the price and size of each bottle. 1.1.6 Calculate the diluted amount of juice (mixed water and concentrate) that can be mixed from each bottle. 1.1.7 Suppose the learners had 50 litres of diluted juice mixed in the ratio 1:5. Determine the amount of the concentrate and water needed in the mixture, round off to the nearest whole number. 1.1 8.
