Document Summary

Which of the following activities describes the opportunity cost of watching a play in a theater? the value of the highest valued alternative that must be forgone because of the time and money required to watch the play. Using a production possibilities curve, a technological advance that increases the amount of output for both goods while using the same amount of inputs would be illustrated by which of the following? an outward shift of the curve. Sally wishes to spend more time this week studying for her classes. Using the idea of a production possibilities curve, and assuming sally is currently spending all of her time efficiently, sally can spend more time studying this week only if she spends less time doing other things. The curve that shows the relationship between the price of a good and the quantity that consumers are willing to purchase at each price is the demand curve.

Q1. The following table shows the relationship between outside temperature (T) and number of hot drinks sold (Q).

Outside temperature (T)	Number of hot drinks sold(Q)
0 ⁰F	1000 cups
20	900
40	800
60	700
80	600

a. Graph and briefly explain the relationship. Put the number of hot drinks sold (Q) on the vertical axis and outside temperature (T) on the horizontal axis.

b. Compute the slope of the line? Y-intercept? Show your work.

c. Construct the equation that represents this line. Predict the number of hot drinks sold (Q) at 26 ⁰F. Show your work.

Q2. Discuss the opportunity costs of the following cases, respectively.

a .Go to the movie theater and watch a movie instead of studying for a midterm exam.

b .Suppose that an economyâs PPF is a straight line, rather than a concave curve. What would this say about the nature of marginal opportunity cost as production is shifted from one good to the other?

Q3. Dreamlandâs production possibilities schedule is as follows:

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

POINT	Capital Goods	Consumption Goods

E	8	0

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

a. Draw the production possibilities frontier. Put Capital Goods on the horizontal axis and Consumption Goods on the vertical axis.

b. If this economy is at point C, what is the opportunity cost of one more capital good (i.e., marginal opportunity cost)?

d. Suppose that Dreamland has two possible choices in the future: it devotes only 5% of its resources to producing capital goods over each of the next 10 years, whereas it devotes 20%. In which case is Dreamland likely to experience more rapid economic growth in the future? Explain your reasoning.
