    Here are the answer choices. A. 1/2x + 3,200=26,300 B. 2x – 3,200 = 26,300 C. 1/2x - 3,200 = 26,300 D. x + 1/2x + 3,00 = 26,300

    That's what I need help figuring out. If someone can run me through the correct process.

    The correct process is thinking about it. If x is last year's population, What does ½x mean? What does 2x mean? What does x + ½x mean?

    1/2x= half of last years population? 2x= twice the amount of last years population? x + 1/2x= last years population plus half last years population?

    Knowing that, can we eliminate choices?

    Yes we can eliminate A, B and C unless I'm mistaken. Also the 3,00 in D is suppost to be 3,200, but I made a typo.

    Why are we eliminating A or C? Do they, or do they not refer to ½x?

    I'm beginning to think it's A.

    D starts with x and then add ½x - That's no good. C starts with ½x, but subtracts 3200. -- That's no good. B starts with 2x -- That's no good. A starts with ½x and adds 3200. That's exactly what is needed. Don't begin to think... Prove it!
