QUESTION 4 Continue with the question. Now, let's estimate fixed costs and unit variable costs using account classification method. FC = $ VC = $ unit VC = $ So, the total cost is calculated as FC + unit VC * volume = $ Based on the formula, we can estimate that the total cost of producing 250 units is $ QUESTION 5 Use the following data for the 4th quarter of 2029: month activity volume (#units) total costs October 80 $4,900 November 75 $5,000 December 100 $6,000 a) Estimate fixed costs and unit variable costs using the high-low method. unit VC = $ FC = $ b) Based on the estimates from (a), what is the cost of producing 90 units? TC = FC + unit VC * volume = $ + volumne
