Let the allowed variation be v ounces. Boxes that cannot be sold satisfy
|weight − 18| > v,
i.e. weight < 18 − v or weight > 18 + v.

On a number line this is shown by two rays:
- an open circle at 18 − v with a ray extending left to −∞,
- an open circle at 18 + v with a ray extending right to +∞.

(If the problem gives a specific v, substitute it for v in the two endpoints.)
