The value of a particular car dropped from 25,000 in may 21,000 in october.find the rate of change in value

  • algebra -

    4000/25000 = 4/25 = .16

  • algebra -

    Hmmm. I would have said

    5 months to drop 4000 = -800$/month

    Don't think we're talking % change here, since we were asked for a rate, which is usually measured in units/time.

    Pick the correct interpretation.
