Answer:
6%
Explanation:
As per given data
Quarter   Real GDP ($billions)   Long-Run Trend of Real GDP ($billions)
  1            4,000                  4,000
  2           4,160                   4,120
  3           4,326                   4,244
  4           4,413                   4,371
  5           4,501                   4,502
  6           4,591                   4,637
  7           4,499                   4,776
  8           4,409                   4,919
  9           4,673                   5,067
  10           4,954                   5,219
  11           5,252                   5,376
  12           5,376                   5,537
Growth of GDP = (DGP of Current/recent period - GDP of Prior period) / DGP of Prior period
In this question prior period is quarter 10 and current /recent period is quarter 11.
So, formula will be
Growth of GDP = (DGP of quarter 11 - GDP of quarter 10) / GDP of quarter 10
As we need to calculate the real GDP growth the formula will be as follow
Growth of real GDP = (Real DGP of quarter 11 - Real GDP of quarter 10) / Real GDP of quarter 10
Growth of real GDP = ($5,252 billion - $4,954 billion) / $4,954 billion
Growth of real GDP = $298 billion / $4,954 billion
Growth of real GDP = 6.02% = 6%
