Real Y=AE Aggregate Expenditure (AE) AE, C B A 45 Real GDP (Y) The Y-axis is labeled Real Aggregate Expenditure (AE), and the X-axis is labeled Real GDP (Y). The 45 line starts at the origin and rises to the right at a 450 angle. The 45 line is labeled Y=AE. One aggregate expenditure line, labeled AE1, starts at a point on the Y-axis and rises to the right with a slope that is less steep than the 45 line. AE1 has three points on it, labeled from left to right A, B, and C. Point B is where AE1 intersects the 450 line. Point A is closer to the Y-axis than Point B, while Point C is farther from the Y-axis than Point B. According to the figure above, at what point is aggregate expenditure less than GDP? none of these options are valid OB A
