Question

A local factory manufactures popcorn. A regular bag should weigh 16 ounces. Twice a week, the factory manager spot checks the weight of bags to make sure the equipment is accurately filling the bags.

The company allows for weight to vary up to 0.25 ounces. In other words, the difference between the actual weight, w, and the expected weight, 16, can be at most 0.25.

Choose an inequality that best represents the scenario.

Answer 1

|w - 16| ≤ 0.25

(Equivalently: 15.75 ≤ w ≤ 16.25, or -0.25 ≤ w - 16 ≤ 0.25.)
