(4) 2.1.2 Determine the point where the selling price is the same as cost price. 2.1.3 Draw the two graphs on the same set of axes provided. (on answer sheet 2 provided) (6) 2.1.4 If Tinyiko increases the selling price to R3,50, what will happen to the point in Question 2.2. (Show all your calculations). 2.1.5 The selling price is given by the formula Selling Price = R3,00 x K, where K is number of scones. Determine the equation for the cost price. (4)
