QUESTION 2
2.1 Susan intends selling cups of Milo at the local taxi rank for extra money. Milo is a nutritious supplementary drink developed to provide active people with key vitamins and minerals.
ANNEXURE B shows the advertisement from her local store where she intends to buy her stock.
Use ANNEXURE B to answer the questions that follow.

2.1.4 Susan decided to exclude the cost of water when calculating the cost price per cup of Milo.
TABLE 1 below shows how Susan calculated the cost price of ONE cup of Milo.
TABLE 1:
QUANTITY BOUGHT | COST OF INGREDIENTS | AMOUNT USED FOR ONE CUP | COST PER CUP OF MILO |
1 kg Milo | R97,95 | 0,04 kg | A |
1 ℓ milk | R11,99 | B | R1,20 |
2,5 kg sugar | R33,20 | 0,01 kg | R0,13 |
25 foam cups | C | ONE | R1,78 |
50 spoons | R12,75 | ONE | R0,26 |
TOTAL COST | D |
2.1.5 Determine the selling price of ONE cup of Milo if Susan's intended profit margin is 25%. (4)
2.2 Susan started her business one month later and because of the price increase of products, it then cost her R9,50 to make ONE cup of Milo. She calculated that the daily fixed cost was R90,00 and she would be able to sell 100 cups of Milo per day. She will sell the Milo at R12,50 per cup.
Use the information above to answer the questions that follow.
2.2.1 TABLE 2 shows the income from the sale of cups of Milo.
TABLE 2: INCOME FROM THE SALE OF CUPS OF MILO
Number of cups of Milo (n) | 0 | 20 | 30 | 40 | 80 | 100 |
Income in rand (R) | 0 | 250 | 375 | P | 1000 | 1250 |
2.2.2 Susan uses the following formula to determine the cost price of the cups of Milo.
Cost = R90,00 + R9,50 × n where n = number of cups of Milo
TABLE 3 shows the cost price for a number of cups of Milo.
TABLE 3: COST PRICE OF A NUMBER OF CUPS OF MILO
Number of cups of Milo (n) | 0 | 20 | 30 | Q | 80 | 100 |
Cost price in rand (R) | 90 | 280 | 375 | 612.50 | 850 | 1040 |
Calculate the value of Q in TABLE 3 above. (3)
2.2.3 The graph on ANSWER SHEET 1 shows the total income for making up to 100 cups of Milo. Use the information in TABLE 3 to draw another graph representing the cost from the selling of up to 100 cups of Milo. (3)
2.2.4 Use the tables or graphs on ANSWER SHEET 1 to answer the following questions.
2.3 Susan decides to send R1 200 to her sister who is studying in Japan. The exchange rate on that date is 1 yen = R0,10976

3.1.2 The paint is sold in 5 ℓ tins.
Each tin has a radius of 7 cm and a height of 35 cm.
5 ℓ = 5 000 cm3
3.2 The waist-to-hip ratio (WHR) is another way of determining the disease risk related to obesity.
You may use the following formula: Waist-to-hip ratio = waistmeasurement
hipmeasurement
Once the calculation is done, a person's disease risk related to obesity is classified as low, moderate, high or very high, based on their age.
DISEASE RELATED TO OBESITY
AGE GROUP | CLASSIFICATION | ||||
(YEARS) | LOW | MODERATE | HIGH | VERY HIGH | |
MEN | 20–29 | <0,83 | 0,83–0,88 | 0,89–0,94 | >0,94 |
30–39 | <0,84 | 0,84–0,91 | 0,92–0,96 | >0,96 | |
40–49 | <0,88 | 0,88–0,95 | 0,96–1,00 | >1,00 | |
50–59 | <0,90 | 0,90–0,96 | 0,97–1,02 | >1,02 | |
60–69 | <0,91 | 0,91–0,98 | 0,99–1,03 | >1,03 | |
WOMEN | 20–29 | <0,71 | 0,71–0,77 | 0,78–0,82 | >0,82 |

50–59 | <0,74 | 0,74–0,81 | 0,82–0,88 | >0,88 | |
60–69 | <0,76 | 0,76–0,83 | 0,84–0,90 | >0,90 |
Use the information above to answer the questions that follow.
3.2.1 Determine if a 37-year-old man with a WHR of 0,95 has a moderate or a high risk of obesity. (2)
3.2.2 A 50-year-old man has the following measurements: waist = 105 cm ; hip = 92 cm
Calculate this man's WHR. (2)
3.2.3 A woman with a waist of 72 cm has a WHR equal to 0,7826 and is classified as a moderate risk.
