for loosening lug nuts, but you can’t find a jack. Your passenger reminds you that you did pass what
seemed to be a couple of houses or barns about 20 minutes ago, though they were only visible in the
distance, far from the road.
Problem Scenario 3: Does the Job Make F inancial Sense?
You have been offered part-time work from home, but will be required to either: work two weekends
every month, 12 hours each on Saturday and Sunday, or miss one class per week (always the
same class, which you must pass and cannot drop) remaining at home so that you’re available for
teleconferencing should your assistance be needed. If you elect to work the weekends, you’ll have
to drop from part-time (50%) work at the bookstore, which pays $1 over minimum wage, but gives
you a 20% discount on your books for every term, and work only 25% time losing the discount on
your books. If you choose instead to miss one class per week, the results will include having to spend
twice as much time doing homework for that class, hiring a tutor at a cost of $1.50 over minimum
wage for 4 hours per week, and quite possibly a loss of one letter grade simply due to the classes
you missed.

1. What is the purpose (why) of each step of the methodology?
2. What are the functions (what & how) and characteristics (when & where) of each step in the
methodology?
