Final answer:
Without specific data regarding the petty cash transactions, it is not possible to calculate the total paid from petty cash for October 2019. Additional financial details are also needed to advise Peter on his ability to meet expenses and plans to move out.
Step-by-step explanation:
To calculate the total paid from petty cash in October 2019, specific data is required such as the beginning and ending balance of the petty cash, and all expenditures made from the petty cash during the month of October 2019. Without this kind of detailed information being provided, it is not possible to calculate the total paid from petty cash. Therefore, the appropriate answer is B) Need additional data to calculate.
As for the second part of the question, subjects like personal finance might be relevant, but again, without detailed information about Peter's expenses and each of the mentioned salaries, it is impossible to determine whether Peter would be able to meet his expenses with the different salaries. For Peter's considerations of moving out of his parents' house, typically the advice would revolve around ensuring that his income exceeds his expenses, including the additional costs of living independently, and that he has a budget and savings plan in place.
