Preston solved the inequality and graphed it on the number line. Which of the following is the inequality that he solved?

A. 2.1x+5.6≥8.75

B. 0.9x+2.8≤5.95

C. 5.6x−18.9≤0.7

D. 3.4x−1.2≥4.75

Unfortunately, without the inequality that Preston solved, it is not possible to determine the correct answer. Please provide more information or options.
