1. The problem involves interpreting a line graph showing sales units and revenue for January, February, and March. 2. The vertical axis represents the number of units sold, ranging from 0 to 3500. 3. The horizontal axis shows sales units on the left and revenue on the right. 4. Each month is represented by a colored line: January (purple), February (blue), and March (green). 5. The lines start near zero on the sales units side and rise to values between 2500 and 3500 on the revenue side. 6. To analyze, note the approximate revenue values for each month based on the graph's vertical scale. 7. For example, January's revenue is near 3500, February's near 3000, and March's near 2500 units sold. 8. This suggests January had the highest revenue, followed by February and March. 9. The graph visually compares sales units and revenue trends over the first quarter. 10. Understanding this helps in assessing monthly performance and planning.
