Month Number of Copies Total Copy Cost January 40,000 $3,500 February 35,000 $3,200 March 60,000 $4,100 April 80,000 $5,100 May 85,000 $5,600 June 75,000 $4,800 July 82,000 $5,300 August 105,000 $6,000 Required a. Prepare a scattergraph of the cost information and then choose a line that you believe best represents the cost function. Represent your chosen line with a cost equation of the form y = mx + b. Show your calculations. Using the high-low method, what is the variable cost per copy? Using the high-low method, what is the fixed cost per month? d. Using the high-low method, represent the cost function with a cost equation of the form y = mx + b. Using your cost equation from part (a), provide your best estimate of the copy costs for September if 80,000 copies will be made. Why does your estimate differ from the $5,100 cost incurred in April?
