    TEAS skill review

    This question tests percent increase, a concept that can appear in the TEAS math section. Read the prompt carefully, identify the rule or evidence being tested, and eliminate options that do not directly satisfy it.

    Why the other choices are incorrect

    The remaining choices conflict with the relevant fact, calculation, language convention, or passage evidence. Check every option against the exact wording of the question rather than choosing an answer that is only generally related to the topic.
