You have received the part drawing for a typical lathe part that will require turning, facing, grooving, boring, and threading as it is machined from a casting. See Figure 26-C. Unfortunately, you do not yet know how many of these parts will be ordered this year, so you do not know what the build quantity will be .To be prepared, you have developed some cost data for the manufacture of the part by four different lathe processes (see Table 26- A). Complete the table by determining the run cost per batch, the cost per unit at the various quantities, and the total cost per batch.Answer the following questions regarding this situation:
