What is an incorrect subject-verb agreement?
An incorrect subject-verb agreement occurs when a writer is unable to correctly align the subject in a sentence with the verb in it.
Thus we can see in this sentence that when the subject, anything, was used which is a singular subject, the corresponding verb should be in the plural form. So, costs, instead of cost should have been used for this sentence.
