Answer:

#n >= 100#

Explanation:

This phrase seems like it is talking about a count of items rather than some kind of continuous measurement. So choose a variable name like #n#, which would typically be used to stand for an integer quantity, rather than #x# or #z#, etc.

If you wanted to be explicit about #n# being an integer, you could write #n in ZZ#, which means #n# is in the set of all integers (#ZZ#).

The compound symbol #>=# means that the expression to the left is greater than or equal to the expression on the right.

In our case #n >= 100# means #n# is greater than or equal to #100#.

In other words #n# is at least one hundred.
