Key Question:

Question 1: The following table shows nominal GDP and an appropriate price index for a group of selected years. Compute real GDP. Indicate in each calculation whether you are inflating or deflating the nominal GDP data.

Year	Nominal GDP Billions,	Price Index (1996 = 100)	Real GDP, Billions
1960	$ 527.4	22.19	$____
1968	911.5	26.29	$____
1978	2295.9	48.22	$____
1988	4742.5	80.22	$____
1998	8790.2	103.22	$____

Question 2: Suppose an economy's real GDP is $30,000 in year 1 and $31,200 in year 2. What is the growth rate of its real GDP? Assume that population is 100 in year 1 and 102 inyear 2. What is the growth rate of GDP per capita?

Question 3: If the CPI was 110 last year and is 121 this year, what is this year's rate of inflation? What is the "rule of 70"? How long would it take for the price level to double if inflation persisted at (a) 2, (b) 5, and (c) 10 percent per year?

Question 4: Graph the accompanying demand data, and then use the midpoint formula for E_d to determine price elasticity of demand elasticity of demand for each of the four possible $1 price changes. What can you conclude about the relationship between the slope of a curve and its elasticity? Explain in a nontechnical way why demand is elastic in the northwest segment of the demand curve and inelastic in the southeast segment.

Product Price	Quality Demanded
$5	1
4	2
3	3
2	4
1	5

Question 5: A firm has fixed costs of $60 and variable costs as indicated in the table on the following page. Complete the table and check your calculations by referring to question 4 at the end of Chapter 23.

1. Graph total fixed cost, total variable cost, and total cost. Explain how the law of diminishing returns influences the shapes of the variable-cost and total-cost curves.

2. Graph AFC, AVC, ATC, and MC. Explain the derivation and shape of each of these four curves and their relationships to one another. Specifically, explain in nontechnical terms why the MC curve intersects both the AVC and the ATC curves at their minimum points.

3. Explain how the location of each curve graphed in question 7b would be altered if (1) total fixed cost had been $100 rather than $60 and (2) total variable cost had been $10 less at each level of output.

Total Product	Total Fixed Cost	Total Variable Cost	Total Cost	Average Fixed Cost	Average Variable Cost	Average Total Cost	Marginal Cost
0	$___	$0	$___	$___	$___	$___	$___
1	___	45	___	___	___	___	___
2	___	85	___	___	___	___	___
3	___	120	___	___	___	___	___
4	___	150	___	___	___	___	___
5	___	185	___	___	___	___	___
6	___	225	___	___	___	___	___
7	___	270	___	___	___	___	___
8	___	325	___	___	___	___	___

ROI analysis using DuPont model:

a) Firm D has net income of $27,900, sales of $930,000, and average total assets of $465,000. Calculate the firm's margin, turnover, and ROI.

b) Firm E has net income of $75,000, sales of $1,250,000, and ROI of 15%. Calculate the firm's turnover and average total assets.

c. Firm F has ROI of 12.6%, average total assets of $1,730,159, and turnover of 1.4. Calculate the firm's sales, margin, and net income.

3. Given: Selling price per unit, $30; total fixed expenses, $33,000; variable expenses per unit, $14.

Find total sales in units to achieve a profit of $7,000, assuming no change in selling price.

4. Given: Sales, $50,000; variable expenses, $20,000; fixed expenses, $20,000; net income,

$10,000. Assume no change in selling price; find net income if activity volume increases 10%.

5. Given: Selling price per unit, $40; total fixed expenses, $80,000; variable expenses per unit, $30.

Assume that variable expenses are reduced by 20% per unit, and the total fixed expenses are increased

by 10%. Find the sales in units to achieve a profit of $20,000, assuming no change in selling price.
