The following chart shows three different costs: Cost A. Cost B, and Cost C. For each cost, the chart shows the total cost and cost per unit at two different volumes within the same relevant range. Based on this information, identify each cost as fixed, variable, or mixed. Explain your answers. At 1,000 units At 4,000 units Total Cost Cost per Unit Total Cost Cost per Unit Cost A $ 75,000 $ 75.00 $ 75,000 $ 18.75 Cost B $ 6,000 $ 6.00 $ 24,000 $ 6.00 Cost C $ 32,000 $ 32.00 $ 68,000 $ 17.00 Cost A is a V Total costs and the per unit costs as the volume increases. Cost B is a Total costs and the per unit costs as the volume increases. Cost C is a Total costs and the per unit costs as the volume increases
