Lisa should be making at least
from her business before quitting her full-time job.
Step-by-step explanation:
Quitting a full-time job and investing the whole work time that we have on a business includes various risks and break-through. Here, Lisa earns a sum of 6000 dollars from her full-time job. So, if she has to decide on quitting it and continuing her business, she must think rationally on the financial factors which are the backbone of any business.
She can quit the job only if she gets at least 6000 dollars (that she was getting from her full-time job) from her business so that she can manage all her expenses which would be considered to be a rational decision.
Logical decisions that are made after deep analysis are said to be rational decisions.
