One type of systematic error arises because people tend to think of benefits in percentage terms rather than in absolute dollar amounts. As an example, Samir is willing to drive 20 minutes out of his way to save $4 on a grocery item that costs $10 at a local market. But he is unwilling to drive 20 minutes out of his way to save $10 on a laptop that costs $400 at a local store. In percentage terms, how big is the savings on the grocery item? On the laptop? In absolute terms, how big is the savings on the grocery item? On the laptop? If Samir is willing to sacrifice 20 minutes of his time to save $4 in one case, shouldn’t he also be willing to sacrifice 20 minutes of his time to save $10?
The following table shows the quantity D of wheat, in billions of bushels, that wheat consumers are willing to purchase in a year at a price P, in dollars per bushel.
D = quantity of wheat

In economics, it is customary to plot D on the horizontal axis and P on the vertical axis, so we will think of D as a variable and of P as a function of D.
(a) Show that these data can be modeled by a linear function.
For each increase of 0.50 in D there is of in P.
Find its formula. (Use P for price and D for quantity.)P =
−.6d+265
(b) Add the graph of the linear formula you found in part (a), which is called the market demand curve, to the following graph based on the following table for market supply curve.

4. a. Suppose that you are on a deserted island and can produce either 32 tons of coconuts OR 16 tons of pineapples. Draw the PPF representing this situation. Assume that coconuts are on the x-axis. Also assume that the PPF is linear. Clearly label your graph. b. For each of the following combinations say whether they are attainable (feasible) or unattainable (infeasible), based on the above information. If they are feasible, say whether they are efficient or inefficient. Also, label the three points on the graph above. (i) 8 tons of coconuts and 12 tons of pineapples: (ii) 16 tons of coconuts and 3 tons of pineapples:

- Upscale hotels in the United States recently cut their prices by 20 percent in an effort to bolster dwindling occupancy rates among business travelers. A survey performed by a major research organization indicated that businesses are wary of current economic conditions and are now resorting to electronic media, such as the Internet and the telephone, to transact business. Assume a company’s budget permits it to spend $5,000 per month on either business travel or electronic media to transact business. Graphically illustrate how a 20 percent decline in the price of business travel would impact this company’s budget set if the price of business travel was initially $1,000 per trip and the price of electronic media was $500 per hour. Suppose that, after the price of business travels drops, the company issues a report indicating that its marginal rate of substitution between electronic media and business travel marginal rate of substitution between electronic media and business…arrow_forwardCome up with two variables that, in your view, are related, indicate the name of these variables as well as why these variables are related; determine which variable is the dependent variable and which one is the independent variable.
