The inequality that Winston can use to determine the minimum number of signatures is 3x ≥ 57.
The first step is to determine which inequality sign would be used.
The following are inequality signs and what they mean:
> means greater than
< means less than
≥ means greater than or equal to
≤ less than or equal to
The sign that would be used is the greater than or equal to sign - ≥ . This is because the number of signatures can be either equal to 80 or greater than 80.
The next step is to determine the least number of signatures needed : 80 - 23 = 57
3(number of signatures they would get) ≥ 57
3x ≥ 57
