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. Write down an equation that can be used to calculate the income. (2)
3. Identify the independent variable in TABLE 2. (2)

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

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)

QUESTION 3
3.1 The Bambanani Crèche in Bethlehem bought the cubic blocks below from an auction. They have a side length of 45 cm. On two opposite sides of the block is a circular hole in the face of the block. They want to use the blocks as chairs for the children.

3.1.1 They intend painting the chairs green with Dulux all-purpose paint.

1. Calculate the area (in cm²) of ONE of the faces of the block that does not have a circular hole.
   You may use the following formula:
   Area of square = side × side (3)
2. Show that the total surface area (area of the faces with circular holes + area of the faces without circular holes) = 11 582,869 cm2.
   You may use the following formula:
   Area of circle = π × radius2, and using π = 3,142 (5)
3. The paint has a spread rate of 1,8 mℓ of paint per 15 cm².
   Calculate the total amount of paint, rounded to the nearest litre, needed to paint 12 chairs with ONE coat of paint. (4)

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

1. Write down the diameter of the tin. (2)
2. Calculate the height of the paint in the tin:
   You may use the following formula:
   Volume of a cylinder = π × (radius)2 × height, where π = 3,142 (3)

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

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.

1. State ONE possible age group of this woman. (2)
2. Calculate the woman's hip measurement. Round off your answer to the nearest cm. (3)

1. From J2 turn left and walk towards the aisle
2. He turns left and continue straight until he reaches the front of the coach
3. He then turns right and sits in the middle seat
   Write down his new seat number. (2)
