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.
NOTE:

  • 1 mt of the paint covers a surface area of 50 cm2
  • 1 inch = 25 mm 

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.

 cylinder

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)

QUESTION 4

Ms Bobby decided to open a business that sells sportsware sets with printed school logos.
Her start-up cost to purchase the machinery and supplies for the business was R10 000. She buys the T-shirts at R50,00 each and the shorts at R35,00 each. It costs a further R10,00 per item to print a school logo on each item.
She sells the T-shirt and shorts as one set of sportsware for R125,00

[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)

  1. Show how the R105 in the formula above was determined. (3)
  2. Calculate her total cost for 500 sets of sportsware. (2)

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   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

  1. Write down the number of sportsware sets that must be sold to break even and give the income at the break-even point. (2)
