Use the blue points (circle symbol) to plot the Real GDP in each of the years listed. (Note: Plot
your points in the order in which you would like them connected. Line segments will connect
the points automatically.) Next, place the black point (plus symbol) on the graph to indicate
the point on the Real GDP curve that definitely represents a peak. Finally, place the grey point
(star symbol) on the graph to indicate the point on the Real GDP curve that definitely
represents a trough.

Based on the graph, in which of the following years did the economy experience a peak? Check all that apply.
Once again, consider the following data on a hypothetical country's Real GDP from 1980
through 1988.
ANNUAL CHANGE IN REAL GDP (Percent)
3
Calculate the percentage change in Real GDP in each of the years shown. (Hint: The
percentage change in Real GDP captures the change in GDP from the previous year to the
current year. For example, you can calculate the percentage change for 1981 by finding the
change in GDP from 1980 to 1981, dividing this change by the level of GDP in 1980, and then
multiplying the result by 100.)

Use the orange points (square symbol) to plot the results of your calculations on the following
graph. (Hint: Round to the nearest percent.) For each year, plot the percentage change from
the year before. (Hint: For example, you should plot the growth rate from 1980 to 1981 with
a horizontal coordinate of 1981.)
