Question

Solve the inequality 47.75 + x Less-than-or-equal-to 50 to determine how much more weight can be added to Li’s suitcase without going over the 50-pound limit. What is the solution set?
x Less-than-or-equal-to 2.25
x Less-than-or-equal-to 2.75
x Greater-than-or-equal-to 2.25
x Greater-than-or-equal-to 2.75

Answer 1

47.75 + x ≤ 50
Subtract 47.75: x ≤ 50 − 47.75 = 2.25

So the solution is x ≤ 2.25 (you can add at most 2.25 pounds).
