Thinking About Next Year

I'm trying to make decisions about high school courses for next year. My biggest question is math. Is Algebra II really necessary? Gabriel and Hannah have no plans for careers in engineering or other areas that require higher math. Gabriel is considering a degree in business administration or management. The college he is considering does not require Algebra II so I am asking those with more experience and insight than myself in this area, do we need to take it? Your input (i.e. comments) is highly appreciated.
