Bryce Allen · Accepted Answer

Final Answer : B, Explanation :   To solve the inequality   2.2 x + 4 ≤ 14.4 2.2x + 4 \leq 14.4 2.2 x + 4 ≤ 14.4  , subtract 4 from both sides to get   2.2 x ≤ 10.4 2.2x \leq 10.4 2.2 x ≤ 10.4  . Then, divide both sides by 2.2 to get   x ≤ 4.7272... x \leq 4.7272... x ≤ 4.7272...  , which rounds to   x ≤ 4.73 x \leq 4.73 x ≤ 4.73  , making option B correct.
