The Austin Manufacturing Company wants to develop a cost estimating equation for its monthly cost of electricity. It has the following data: Month Cost of Electricity Direct Labor Hours January P6,750 1,500 April 7,500 1,700 July 8,500 2,000 October 7,250 1,600 12. Using the high-low method, what is the best equation? 13. At an activity level of 2,500 labor hours, compute for the total mixed cost Items 14 to 16 are based on the following information: Pure Foods wishes to analyze the fixed and variable components of the semi-variable costs. The following information is available: Month Units Cost Month Units Cost (in pesos) January 1,000 12,000 April 800 P11,000 February 700 10,000 May 1,400 18,750 March 1,100 14,000 June 1,200 15,000 14. Using the high-low method, how much is the total fixed cost per month? 15. Using the high-low method, how much is the unit variable cost per month? 16. At an activity level of 900 units, how much is the total mixed cost? Items 17 and 18 are based on the following information: DDD Inc. incurred the following costs on JO 201 for manufacturing of 500 units: Original cost accumulation: Direct Materials P500,000 Direct Labor 400,000 Factory Overhead 100,000 Direct cost of reworking 100 units: Direct Materials P100,000 Direct Labor 200,000 Factory Overhead 50,000 17. What is the cost per unit of JO 201 if the rework costs were attributable to the exacting specification of JO 201? 18. What is the cost per unit of JO 201 if the rework costs were attributable to internal failure
