Use ANNEXURE A and the information above to answer the questions that follow.
1.1.1 Communication costs decreased by 4,402% from 2015 to 2016. Calculate (to the nearest thousand rand) the communication costs for 2016. (4)
1.1.2 The SANBS imports 75% of its product testing material and consumables. Explain what possible impact a weakening of the rand will have on their total profit for the year. (2)
1.1.3 Compare, showing ALL calculations, the 2015 and 2016 percentage profit for the SANBS.
You may use the following formula:
1.2 ANNEXURE B shows the individual tax rates for the 2016/2017 tax year.
One of the SANBS directors, who is 68 years old, earned a taxable income of R663 000 during the 2016/2017 tax year.
Calculate the total income tax this director has to pay on his annual taxable income (ignore medical aid credits). (6)
1.3 During 2016, a total of 110 000 South Africans in the age group 16 to 19 years donated blood. The SANBS decided to appeal to eligible high-school learners to donate blood. Their target is to increase the number of donors in this age group by an annual growth rate of 9,6%, compounded over the next two years.
Calculate, showing ALL calculations, the targeted number of blood donors in this age group for 2018. (4)
Use the bar graph above to answer the questions that follow.
1.4.1 Give a possible explanation for including an ‘Unknown’ category as a racial group. (2)
1.4.2 Describe a possible trend relating to the percentage black donors. (2)
1.4.3 Explain why it cannot be said with certainty that the number of Asian donors remained the same from 2014 to 2016. (2)
1.4.4 The total number of donors in 2016 was 490 914. This total donor base grew marginally from the previous year by 1,02%.
(a) Calculate the number of donors in 2015. (2)
(b) Hence, determine (rounded off to the nearest 10) the number of white donors in 2015. (4)
1.5.1 Write down the probability of randomly selecting a South African who is classified in the O blood group. (2)
1.5.2 Identify the blood group of a recipient that has a 100% probability of being able to receive blood from any donor blood group. (2)
1.5.3 Verify, with a reason, whether it is most likely for an 0¯ blood group recipient to be able to receive blood from any donor blood group. (3)
