Problem 10-1AC The controller of Sunland Production has collected the following monthly expense data for analyzing the cost behavior of electricity costs. Total January February March 320 460 April 450 Total Electricity Costs Machine Hours $2,490 250 3,000 3,530 4,740 695 3,160 4,900 790 4,130 3,090 590 5,170 680 4,220 3,290 7,530 810 May June July August September October November December 625 610 320 Determine the foced- and variable-cost components using the high-low method. Fored-costs Variable-costs What electricity cost does the cost equation estimate for a level of activity of 460 machine hours? Electricity costs By what amount does this differ from March's observed cost for 460 machine hours? Amount differ (c) What electricity cost does the cost equation estimate for a level of activity of 790 machine hours?
