1.1.3 Determine the probability (in simplified form) of randomly selecting a Friday visit to the Rand Show. (3)
1.1.4 The family visited the Rand Show on 23 April 2017. Mrs Abrahams stated that if the family had visited the Rand Show on 20 April instead of 23 April, they would have saved more than 35% on the total cost of the tickets. Verify, showing ALL calculations, whether her statement is valid. (9)
1.2
The South African government offers social support to its citizens by providing social grants to qualifying citizens. The bar graph and table on ANNEXURE A shows the number of citizens who receive social grants and the number of citizens employed per province. |

1.2.2 Give ONE reason why governments usually provide grants to some of their citizens. (2)
1.2.3 State, giving a reason, whether the data in ANNEXURE A could also easily be represented using a single pie chart. (3)
1.2.4 Calculate the percentage of citizens receiving social grants in Limpopo. (6)
1.2.5 Gauteng and the Western Cape are the only TWO provinces with more employed citizens than the number of citizens receiving social grants. Determine, using unit ratios, which ONE of these two provinces have more employed citizens than citizens receiving social grants. (6) [37]
QUESTION 2
2.1 ANNEXURE B shows the credit card statement of Mr Son.
Use the information in ANNEXURE B to answer the questions that follow.
2.1.1 Determine the number of days covered by this credit card statement. (2)
2.1.2 Use the transaction details and show, with calculations, how the closing balance was determined. (5)
2.1.3 Explain why the bank omitted some digits from the account number on the statement. (2)
2.1.4 The bank offers an insurance option on the outstanding balance of the credit card account by charging a rate of R3,50 per R1 000 (or part thereof) on the outstanding balance.

2.1.5 Interpret the amount for balance brought forward for this statement. (2)
2.1.6 Give ONE possible reason why Mr Son might purchase goods using his credit card instead of paying cash for the goods. (2)
2.2
Mr Son travelled from his home directly to a bank 34 km away. He travelled at an average speed of 85 km per hour and arrived at the bank at 12:10. |
Verify, showing ALL calculations, whether Mr Son left his home at exactly 11:40. The following formula may be used:
Distance = average speed x time (5)
2.3
Use TABLE 2 above to answer the questions that follow.
2.3.1 Give ONE possible reason why there is no recorded revenue data for Japan. (2)
2.3.2 Calculate the number of book titles published for Brazil if the range of the number of book titles published is 463 223. (3)

QUESTION 3
3.1
An organiser of a science fair has to produce rectangular display boards. The external dimensions of each board are 48 inches by 36 inches. The front surfaces of the boards must be spray-painted with one layer of non-reflective white paint.
|
Determine, showing ALL calculations, whether 5 litres of the paint would be enough to spray paint 25 display boards. The following formula may be used: Area = length x width (10)
3.2
The organiser of the science fair has a choice of two cylindrical containers ( as shown below) for display purposes. A decorative label with a 1 cm overlap will be placed right around the container completely covering the curved surface only.
|
Verify, showing ALL calculations, whether cylinder B would require less material to make the decorative labels.
The following formula may be used:
Curved surface area of cylinder = n x diameter x height, where it = 3,142 (7)
3.3
ANNEXURE C shows the floor plan of the layout of the exhibition stands allocated to countries for the International Higher Education Fair. |

3.3.3 The organisers of the fair identified the most outstanding exhibition stand. Determine the probability that this outstanding exhibition stand will NOT be a stand from China. (3)
3.3.4 An electrician was called to attend to a technical issue at one of the exhibition stands. He followed the route listed below.
Identify the delivery entrance used by the electrician and the stand number with the technical issue. (4)
3.3.5 Identify which Chinese stand is closest to the information centre. (2)

QUESTION 4
Ms Bobby decided to open a business that sells sportsware sets with printed school logos. [Adapted from www.bidorbm .co.za] |
Use the information above to answer the questions that follow.
4.1.1 The formula to calculate her total cost is as follows:
Total cost = R10 000 + R105 x (number of sportsware sets)
4.1.2 TABLE 3 below shows the relationship between the number of sets of sportsware sold and her total income for the sets.
TABLE 3: NUMBER OF SPORTSWARE SETS SOLD AND THE TOTAL INCOME (in thousand rand)
NUMBER OF SPORTSWARE SETS SOLD | 0 | 200 | 400 | 500 | A | 800 | 1 000 |
TOTAL INCOME (in thousand rand) | 0 | 25 | 50 | 62,5 | 87,5 | B | 125 |
Determine the missing values A and B. (6)
4.1.3 Use TABLE 3 and the equation in QUESTION 4.1.1 above to draw TWO straight-line graphs representing the total cost and total income for up to 1 000 sets of sportswear.
Draw clearly labelled graphs on the grid provided on the ANSWER SHEET. (7)
4.1.4
4.2
Determine, showing ALL calculations, which ONE of the two scales (1 : 3 or 1 : 4) should be used so that the set of sportsware fits on the A4 page. (6)
4.3
Ms Bobby is interested in selling her sets of sportsware over the Internet. The line graphs in ANNEXURE D show preferred goods purchased over the Internet and in-store. |
Use ANNEXURE D to answer the questions that follow.
4.3.1 Give ONE possible reason why some people prefer to buy goods over the Internet rather than in-store. (2)
