Per capita GDP starts at $909 and grows by 5.2% each year for 5 years. Then it continues to grow at 5.2% for 75 more years. Scenario 2 - A Depression Before Growth Per capita GDP starts at $909 but a recession lasting for 5 years shrinks GDP per capita by 14% for each of those years. Then the economy recovers and grows by 5.2% for the next 75 years. How much lower is per capita GDP at the end of Scenario 2 compared to Scenario 1? Note: If the Great Depression never happened, and the U.S. experienced normal growth over those years instead, GDP per capita today might be as high as $180,000. Since our GDP per capita is more like $60,000 today, that means we have $120,000 less per person today because of the Depression. So, with those numbers, my answer to this question would be "120,000". TL;DR - Enter your answer as a positive number, not a negative one. Round your final answer to two decimal places
