Which graph below shows what happens to her demand for designer shoes? In this graph, the horizontal x-axis represents quantity and is made up of 12 graph squares. The vertical y-axis is also made up of 12 graph squares. Curve S1 begins at x = 1 and y = 1 and ends at x = 6 and y = 11. Curve S2 begins at x = 1 and y = 4 and ends at x = 11 and y = 9. Curve D1 begins at x = 1 and y = 8.5 and ends at x = 9 and y = 2. The dotted curve, D2, begins at x = 4 and y = 10 and ends at x = 12 and y = 3.5. Point P0 is marked on the y-axis at y = 5. Point Q0 is marked on the x-axis at x = 4. Points P0 and Q0 meet at the point where Curves S1, S2, and D1 intersect, at x = 4 and y = 5. In this graph, the horizontal x-axis represents quantity, and the vertical y-axis represents price. Curves D1 and D2 are parallel to each other, beginning in the later x coordinates and
