Explanation:

Step1: Identify quartiles in box - plot

In a box - plot, the box represents the middle 50% of the data. The lower end of the box is the first quartile ($Q_1$) and the upper end is the third quartile ($Q_3$).

Step2: Estimate values from the plot

From the box - plot, the lower end of the box (approximate $Q_1$) is around 490 (in thousands of dollars) and the upper end of the box (approximate $Q_3$) is around 850 (in thousands of dollars).
