Downloaded from hlayiso.com Mathematical Literacy/P2 8 NW/September 2019 NSC QUESTION 4 4.1 Peter, the sales manager at HGM, and his team discussed strategies to improve their sales of perfume. They intend using four different strategies. 4.1.1 The first strategy is to package their perfume using a rectangular bottle and a cylindrical bottle. They have decided to price the bottles differently. The bottles will be filled to 95% capacity. The picture below shows the bottles and the dimensions of the bottles. Cylindrical bottle Rectangular bottle Diameter = 6 cm Length = 5 cm Breadth = 2 cm Height = 1,6 cm Height = 45 mm (a) Why are the perfume bottles not filled to 100% capacity? (2) (b) State, without any calculations and giving a reason for your choice, which bottle of perfume will be priced higher. (2) Copyright reserved Please turn over

Leave your answer in cubic centimetres. The following formulae may be used : Volume of a rectangular bottle = ℓ× × Volume of a cylindrical bottle = ×( ) × The value of = , (8) 4.1.2 The second strategy they discussed was to give a free gift of bath salts to customers who spent more than R500,00. Each bottle of bath salts will be filled using three measuring cylinders of equal dimensions as indicated below. 3 MEASURING CYLINDERS BOTTLE OF BATH SALTS Radius = 2,5 cm Height = 10 cm NB: 1 g = 1 cm3 = 1 ml The bottle of bath salts has a capacity of 600 g. Use calculations to show that the salt granules from three measuring cylinders will fit into the bath salts bottle. You may use the following formula: Volume of a cylindrical bottle = ×( ) × The value of = , (5) Copyright reserved Please turn over

Downloaded from hlayiso.com Mathematical Literacy/P2 10 NW/September 2019 NSC 4.1.3 The third strategy was to sell different types of perfumes with differing ratios of perfume : oil : alcohol. Ratio Type of perfume perfume : oil : alcohol EDT 5 : 90 : 5 EDP 12 : 85 : 3 The manager claimed that the difference in the amount of oil (rounded to the nearest unit) between the two types of perfumes in a 45 mℓ bottle is, 3 mℓ. Verify his claim by showing calculations? (6) 4.1.4 The last strategy is to have monthly competitions where customers can win prizes. The prizes are hidden behind the letters of the word “CONCENTRATION” and the chosen letter is not replaced. The chosen letter is then removed and cannot be chosen again. The first customer randomly chose the letter “R”. Determine the probability that the second letter chosen will be a “C”. (3) 4.2 Paul, who is 52 years old, is an employee at a Research Company. He earned an annual income of R338 000 for the 2018/2019 tax year. · He contributes 7,5% of his basic salary to the pension fund. · He also donates R46 800 per annum to a registered charity organisation.
