Question

Latasha is training for a triathlon, a timed race that combines swimming, biking, and running. Consider the following sentence: Because her pool sessions are helping her swim more quickly, Latasha plans to reduce by 1 hour per week the time she spends training on the bike and increase by 1 hour the time she spends in the swimming pool; however, her husband says that she should stop doing any biking and running and spend all 20 hours per week in the pool. Which basic principle of individual choice does Latasha's plan illustrate that her husband's advice does not?
a. People usually exploit opportunities to benefit themselves.
b. All costs are opportunity costs
c. Resources are scarce.
d. Many decisions are taken using marginal thinking

Answer 1

The principle that Latasha caters for that her husband does not is that d. Many decisions are taken using marginal thinking.

Marginal decision making

• Involves making decisions based on the marginal costs and benefits.
• A person will make a decision that has more benefits than costs.

By swimming more, Latasha would make get the benefit of being better at something she is already good at. If all she does is swimming however, she would incur costs of losing out in the other activities which would surpass the benefits of being good in swimming alone.

In conclusion, option D is correct.
