*****I saw that this question exists in Chegg. However, the answers are mostly not consistent with my homework answers from the professor***

Each store has a manager who is paid a fixed salary. Individual salespeople receive a fixed salary and a sales commission.

For example, if the answer was 23.33%, you need to enter it at .23)
