Final answer:
The student's question refers to the sales mix of different types of computer hard drives sold by Vaughn Manufacturing. The correct types of hard drives in the sales mix are not specified. Figure 12.28 offers a description of a traditional hard disk drive's internal components.
Step-by-step explanation:
The sales mix mentioned in the student's question relates to Vaughn Manufacturing's proportionate sales of different types of computer hard drives. Typically, a sales mix refers to the ratio of different products sold, which can impact overall profitability. In this case, the question implies that Vaughn Manufacturing sells two distinct types of drives, but the correct types are not clearly stated. The student would need to provide the correct types of hard drives that make up the 30/70 split in Vaughn Manufacturing's sales mix.
Figure 12.28 describes the inside of a hard disk drive (HDD), where the silver disk stores information and the stylus-like component - often called a read/write head - interacts with the disk to either read or write data. This description is typical of traditional HDDs that use spinning disks to store data.
