Please solve for Cost B and Cost C all the way across! Thanks

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 Cost B Cost C 75,000 $ 6,000 $ 32,000 S 75.00 $ 6.00 $ 32.00 S 75,000 $ 24,000 $ 68,000 S 18.75 6.00 17.00 Cost A is a fixed cost Total costs stay the same and the per unit costs decrease as the volume increases Cost B is a mixed cost Total costs stay the same and the per unit costs remain constant as the volume increases fixed cost mixed cost variable cost The following chart shows three different costs: Cost A, Cost B, and Cost C.
