QUESTION 1
1.1 The Western Cape water crisis began in 2015 resulting in a severe water shortage in Cape Town.
Hence the province declared Level 6B water restrictions. Level 6B recommends a daily limit of 50 litres per person.
TABLE 1 below is a guide on maximum household water consumption.
TABLE 1: Maximum household water consumption guide

NUMBER OF OCCUPANTS PER HOUSEHOLD MAXIMUM LITRES PER DAY MAXIMUM LITRES PER MONTH
 1  50  1500
 2  100  3000
 6  300  9000
 8  400  12000
 A  750  22500
 30  1500  45000
 50  2500  B

Use the information above to answer the questions that follow.
1.1.1 Calculate the missing values A and B. (4)
1.1.2 Theo stated that the approximate litres per month were calculated for the number of days in July.
Verify, showing ALL calculations, whether this statement is valid. (3)
1.1.3 If you have more than FOUR occupants living on your property, you need to apply for an increase in your water quota.

  • One occupant more than four – an additional 5% is allowed on the maximum litres per day.
  • Two occupants more than four – an additional 10% is allowed on the maximum litres per day.
  • Three or more occupants more than four – an additional 20% is allowed on the maximum litres per day.

ITEM  QUANTITY UNIT PRICE
Jojo tank   1  R12 958,00
Other materials   1  R1 943,70
Labour per hour or part thereof     R129,99

He found out that the installation will take 5 hours 10 minutes on the first day and then 2 hours on the second day.

QUESTION 2
2.1 During winter many children develop coughs. Cough syrups are sold in bottles packed in rectangular prism-shaped boxes.
Children are given cough syrup using a cylindrical measuring cup.
The diagrams below show the bottle, the box and the measuring cup.

Total surface area of a rectangular prism:
= 2(length × width) + 2(length × height) + 2(width ×height)
Volume of a rectangular prism = length × width × height
Total surface area of cylinder = (2π × radius2) + (2π × radius × height)
Volume of a cylinder = π × radius2 × height
Use: π = 3,142
1mℓ = 1 cm3
Use the information above to answer the questions that follow.
2.1.1 Consider the cough syrup box.

  1. Calculate (in cm3) the total surface area of the cough syrup box. (4)
  2. Give a practical reason why a cartoon picture would feature on the box of the cough syrup for children. (2)

2.1.2 Calculate (in cm) the height of the medicine measuring cup if the diameter is 2,52 cm and the volume is 10 mℓ. (4)
2.2 The pharmacy received the following order of cough syrup:

  • 5 large cartons of cough syrup
  • Each carton is packed with 4 layers of cough syrup boxes
  • Each layer has 8 rows of cough syrup boxes
  • Each row has 6 boxes of cough syrup

Calculate the total number of cough syrup boxes the pharmacist received. (4)
2.3 Whooping cough affects the chest and nose and is characterised by a cough that makes a 'whoop' sound.
TABLE 3 below shows data about the reported cases of whooping cough and the percentage of hospitalisation per age group. Some data has been omitted and some reported cases did not indicate the patients' ages.
TABLE 3: Reported whooping cough cases and percentage hospitalised by age group.

2.3.1 N represents the highest number of whooping cough cases for the known age groups. The range for the number of whooping cough cases for the known age groups is 4 527.
Determine the value of N. (4)
2.3.2 Determine the interquartile range (only known age groups) for the reported number of whooping cough cases per age group. (5)
2.3.3 It was stated that the unknown age group makes up 0,5% of the total number of reported cases for whooping cough.
Explain, by means of calculations, why this statement is CORRECT. (5)
