Question

An airline charges an extra fee if a suitcase weighs more than 50 pounds. After packing, Li’s suitcase weighs 47.75 pounds. Which inequality can be used to determine how much more weight can be added to the suitcase without going over the 50-pound weight limit?
47.75 + x < 50
47.75 + x Less-than-or-equal-to 50
47.75 + x Greater-than-or-equal-to 50
47.75 + x > 50

Answer 1

47.75 + x ≤ 50

Solving: x ≤ 50 − 47.75 = 2.25, so up to 2.25 pounds can be added without exceeding the limit.
