In each of the following situations, identify which of the nine
principles is at work.
a. You choose to shop at the local discount store rather than
paying a higher price for the same merchandise at the
local department store.
b. On your spring vacation trip, your budget is limited to
$35 a day.
c. The student union provides a website on which departing
students can sell items such as used books, appliances,
and furniture rather than giving them away to their roommates as they formerly did.
d. You decide how many cups of coffee to have when studying the night before an exam by considering how much
more work you can do by having another cup versus how
jittery it will make you feel.
e. There is limited lab space available to do the project required
in Chemistry 101. The lab supervisor assigns lab time to
each student based on when that student is able to come.
f. You realize that you can graduate a semester early by forgoing a semester of study abroad.
g. At the student union, there is a bulletin board on which
people advertise used items for sale, such as bicycles. Once
you have adjusted for differences in quality, all the bikes
sell for about the same price.
h. You are better at performing lab experiments, and your lab
partner is better at writing lab reports. So the two of you
agree that you will do all the experiments, and she will
write up all the reports.
i. State governments mandate that it is illegal to drive without passing a driving exam.
