Final answer:
The sentence contains two clauses. In the first, 'She' is the subject and 'works two jobs to make ends meet' is the predicate. In the second, 'that' is the subject and 'was her reason for not having time to join us' is the predicate.
Step-by-step explanation:
In the given sentence 'She works two jobs to make ends meet; at least, that was her reason for not having time to join us.' can be divided into two independent clauses. In the first clause, the subject is 'She' and the predicate is 'works two jobs to make ends meet'. For the second clause, the subject is 'that' referring to her working two jobs, and the predicate is 'was her reason for not having time to join us'. Here, both the subjects are noun or pronouns, and the predicates express the actions or states of being related to those subjects.
