To determine which inequality Paolo solved, we need to analyze the given inequalities and their corresponding graphed solutions on the number line.

A. 2.8x<10.5: The solution to this inequality would be x < 10.5/2.8. On the number line, the solutions would be to the left of the point 3.75.

B. 3.7x>14.8: The solution to this inequality would be x > 14.8/3.7. On the number line, the solutions would be to the right of the point 4.

C. 4.9x>19.6: The solution to this inequality would be x > 19.6/4.9. On the number line, the solutions would be to the right of the point 4.

D. 2.1x<8.4: The solution to this inequality would be x < 8.4/2.1. On the number line, the solutions would be to the left of the point 4.

Based on the information given, Paolo solved the inequality 2.1x < 8.4. Therefore, the correct answer is D. 2.1x<8.4.
