(CLO 1, Chapter 2, CMA part 2) (4 marks]: Total production costs of prior periods for a company are listed as follows. Assume that the same cost behavior patterns can be extended linearly over the range of 3,000 to 35,000 units and that the cost driver for each cost is the number of units produced Production units per month 3,000 16,000 $23,700 $86,490 35,000 $178,260 Cost X cost Y 47,280 252,160 551,600 Required: 1. For each of X and Y, determine whether variable, fixed or mixed. (1 mark) 2. Determine the cost equation for each product (if mixed), using the high-low method (1.5 marks) 3.
