Complete the chart, showing manufacturing cost at various levels of production for Company X Volume (units) Cost A Cost B Cost C 10,000 20,000 30,000 40,000 25,000 $25,000 $25,000 $50,000 $33,000 $48,000 $25,000 $100,000 $78,000 Unit cost $8.30 What pattern do you observe in the behavior of unit cost? Explain briefly why this occurs. Develop an equation in the form of Y a +bX to forecast total manufacturing cost. Use this equatioin to forecast total costs at a level of 70,000 units. ldentify one reason why your forecast in c) may be unreliable
