Calculate the percentage change in real GDP in each of the years shown. (Hint: The percentage change in real GDP equals 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.)
Once you've calculated the percentage change for each of the years, use the orange points (square symbol) to plot your results on the following
graph, rounded 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.)
