5. A small businessman needs to produce a large number of coloured photocopies. The content of which changes each week. There are two ways he can do this: Method A: take the job to a printer who charges RM0.08 each for the first 400 copies and RM0.04 each thereafter. Method B: hire a machine which will cost RM40 per week plus RM0.02 per copy. (a) Express the cost of each method algebraically. (b) Draw a graph to show the cost of method A and B. (use 1 cm as 200 copies on x-axis) (4 marks) (5 marks) (c) Find the most economic method for different quantities to be produced algebraically. (5 marks) (d) The businessman considers a third option. He could buy a machine that would pay for at the rate of RM60 per week, but the paper would only cost him RM0.01 per copy. Add this option to your graph. (2 marks) (e) If the businessman needs to produce 6000 copies per week, which method would you recommend? Explain your answer. (4 marks)
