A graph plots price level versus real G D P in billion dollars. A falling line labeled A D is graphed.The horizontal axis is labeled real G D P in billion dollars. The horizontal axis shows a line break between 0 and 500 and ranges from 500 to 800 in increments of 100. The vertical axis is labeled price level. It shows a line break between 0 and 100 and ranges from 100 to 250 in increments of 50. A falling line labeled A D begins at the top-left, passes through A (500, 250), B (600, 200), C (700, 150), and D (800, 100). Refer to the graph, which shows an aggregate demand curve. If the price level increases from 100 to 150, the real output demanded will Multiple Choice decrease by $50 billion. increase by $100 billion. decrease by $100 billion. increase by $50 billion
