Money Left - College Algebra

  • 0:00 - 0:04
    So we know that grant started off with a
    certain amount of money from the venture
  • 0:04 - 0:09
    capital funders. But then he doesn't just
    keep it, he starts to spend it. This means
  • 0:09 - 0:13
    that the right choice must take both of
    these into account, the money that he was
  • 0:13 - 0:17
    given initially and the money that he
    spent so far. The second and last choices
  • 0:17 - 0:21
    only have one of these two things each, so
    that means that neither of them can be
  • 0:21 - 0:26
    right. So I'm going to cross them both
    out. So that just leaves us with these
  • 0:26 - 0:30
    two. Money from funders plus money spent,
    or money from funders minus money spent.
  • 0:30 - 0:34
    Spending money, actually takes away from
    the amount of money that we have. It
  • 0:34 - 0:38
    doesn't add to it. So that means that the
    third choice, right here, money from
  • 0:38 - 0:42
    funders minus money spent must be the
    right answer. Now without even trying
  • 0:42 - 0:47
    we've actually just done some math. I know
    that there aren't any numbers here, but
  • 0:47 - 0:51
    what we've created is called an equation.
    It's called that because of this equal
  • 0:51 - 0:55
    sign right here in the middle. Over doing
    with this equation is showing that these
  • 0:56 - 1:00
    two quantities, the one on the left side
    of the equal sign and the one on the right
  • 1:00 - 1:04
    side. Are equal to each other, or have the
    same numerical value. This is the first of
  • 1:04 - 1:07
    many, many equations that we're going to
    look at throughout this course. And over
  • 1:07 - 1:10
    time you'll learn to do a ton of different
    things with them.
