Final answer:
Without explicit income and expense details, the value of Peter's monthly expenses cannot be determined. Also, without knowing Peter's expenses and the salaries for different jobs, we cannot assess if those salaries would suffice. Peter should evaluate his financial stability before considering moving out.
Step-by-step explanation:
To calculate Peter's monthly expenses based on the information provided, we need a clearer context or some specific numbers related to his income and spending.
However, since there are no explicit details given about Peter's income or spending habits, we cannot accurately determine the value of his expenses. Hence, the value of Peter's expenses cannot be determined with the information currently available.
For question 8, we would need to know the amounts of Peter's monthly expenses, as well as the respective salaries for the various jobs mentioned. Without this, we cannot assess whether the salaries from these jobs would meet his expenses.
As for question 9, advising Peter on moving out of his parents' house without details about his financial readiness, possible expenses, or job situation is not feasible.
It would be prudent to suggest that Peter thoroughly assesses his financial stability, including income and potential living expenses, before making a decision to move out.
