Critical-Thinking Exercises
1. Prices at amusement parks might rise if operators such as Disney and Universal Studios add new
rides. The parks also have to deal with high fuel prices. List as many things as you can think of that parks
like these offer patrons in return for their money. Which of these do you think are directly reflected in the
price of admission?
Answer: Students’ answers will vary. Rides and attractions cost money to build, run, and maintain.
Obviously the admission price reflects all of these costs. What they offer their visitors is fun and other
2. Recording artists earn only about 9 percent in royalties per CD, using a royalty base of retail price less
25 percent for packaging costs. The rest goes to the producer and to cover recording costs, promotion,
copies given away to radio stations and reviewers, and other costs such as videos. What do you think

In the first case, the artist might actually make more money overall. It would happen if the increase in unit

3. Some finance experts advise consumers not to worry about rising gasoline prices, the cost of which
can easily be covered by forgoing one takeout meal a month, but to worry about how high energy prices
will affect the rest of the economy. For example, each dollar-a-barrel price increase is equivalent to a $20
million-a-day “tax” on the economy. Explain what this means.

consumers continue to use about the same amount of energy as the total amount spent on energy would
increase, leaving less money for other consumer products. However, if consumers use less energy, the
