(4)

Mathematical Literacy/P2 5 NW/June 2017 NSC – Grade 11 1.2.2 Write down the formula for calculating the cost of baking loaves of bread in the form: Cost (in rand) = (2) 1.2.3 Use the formula in Question 1.2.2 to calculate the cost for baking 50 loaves of bread. (2) 1.2.4 The graph illustrating income received by Masakhane Bakery from selling loaves of bread is drawn on the ANSWER SHEET. Use the values from Table 1 to draw the graph illustrating the cost of baking loaves of bread on ANSWER SHEET. (5) 1.2.5 Determine the break-even point (2) 1.2.6 Calculate the profit if 200 loaves of bread were sold. (3) 1.2.7 The manager of Masakhane Bakery claims that if they bake 200 loaves and sell all of them, the bakery will make a profit of more than 10% of the cost for baking the 200 loaves. Verify, showing ALL calculations, if the claim is valid. (3) 1.3 Last Push timetable for Bakang Secondary School is provided on ANNEXURE A. The staff agreed that Languages should be given 15 % of the total time for Last Push. Determine, showing ALL calculations, whether 15 % of the total time for Last Push is given to Languages. (4) [32] QUESTION 2 2.1 Palesa and her family own a house in Temba area. They use an average of 324 kWh of electricity a month. The TABLE below shows the electricity tariffs in Palesa’s area. TABLE 3: Residential tariff rates inclusive of VAT for electricity in Palesa’s area Block Usage Charge(c/kWh) Block 1 0 – 350 kWh 117,86 Block 2 350- 600 kWh 163,19 Block 3 > 600 kWh 200,34

(5) 2.1.3 State ONE possible reason why the cost for electricity has increased in that particular month. (2) 2.2 Palesa is a member of the fitness gym. She is 1,54 m tall and weighs 67 kg. The instructor of the gym calculates the body mass index (BMI) on monthly basis to determine the health status of all the members. You may use the following formula: BMI = The TABLE below shows the health status according to the BMI: TABLE 4: Health status according to the BMI BMI Health Status Below 18 kg/m2 Underweight / Malnourished Between 18 kg/m2 and 24,9 kg/m2 Normal Between 24,9 and 29,9 kg/m2 Overweight Above 29,9 kg/m2 Obese Use information above to answer the questions that follow: 2.2.1 Calculate Palesa’s BMI in kg/m2 (rounded off to ONE decimal place). (3) 2.2.2 Identify Palesa’s health status (2) 2.2.3 In a particular month, Palesa lost too much weight such that her health status also changed. Give one possible reason. (2) 2.2.4 One day at the gym, Palesa collapsed and was taken to hospital. On her arrival at hospital, her temperature was 43˚C. Convert her temperature to ˚F (rounded off to the nearest 10˚F).

NOTE: 1 Japanese Yen (¥) = R0,08. (3) 3.1.4 Give ONE example of transport cost. (2) 3.2 Mr. Le Roux’s business of selling fish tanks is growing. He intends to buy bigger tanks that can carry 26 fish. Available tanks at the factory are 30 cm wide, 100 cm long and 60 cm deep. Width = 30 cm Depth= 60 cm length=100 cm NOTE: 1 fish needs at least 7 litres of water 1 000 cm3 = 1 litre Volume = length × width × depth Use the information above to answer the questions that follow: 3.2.1 Calculate the volume of the tank in litres. (3) 3.2.2 Will 26 fish fit in the tank? Justify your answer using calculations. (3) 3.2.3 Convert the volume of the tank to gallons (rounded off to the nearest gallon) CONVERSIONS: 1ℓ = 1,7598 pint and 1 pint = 0,125 gallons (5) [22] TOTAL MARK: 75
