Sarah Ramirez is considering taking a part-time job at a local clothing store. She loves the store and shops there often, but unfortunately, employee discounts are given only to full-time employees. If Sarah takes this job, she would have to withdraw from her Tuesday night basket- weaving class to work. Accepting the job would also mean that Sarah must give up her volunteer work at the local animal sanctuary, an activity that she enjoys a great deal. The new job would pay approximately \($125\) per week but would cost Sarah \($15\) per week in gas. Sarah would be able to keep her Saturday afternoon job at the library that pays \($40\) per week.

A list of factors that Sarah has identified follows. For each one, indicate whether it is relevant or irrelevant to Sarah’s decision.

1. The \($125\) income from the new job.

2. The \($40\) income from the library.

3. The \($50\) nonrefundable registration fee Sarah paid for the basket-weaving class.

4. The $ 15 cost for gas.

5. The \($75\) per month that Sarah spends for clothing.

6. The time Sarah spends volunteering at the animal sanctuary.
