The graph shows the estimated value, in thousands of dollars, of two different investments, Investment A and Investment B, over $x$ years. Investment A is represented by the solid line, and Investment B is represented by the dashed line. What is the positive difference between the initial values of Investment A and Investment B, in thousands of dollars?

(Assume the graph shows two lines: Investment A (solid) starts at (0,20) and increases. Investment B (dashed) starts at (0,10) and increases.)
