So I tried and tried to solve this one, and ultimately had to hit that dreaded “SOLUTION” button to see the answer. In case you’re like me and are determined to try to solve it on your own, here are some helpful hints to solve this one:

  • Keep this answer as short, simple and stripped down as possible. All of the past statement answers in this lesson were very long and wordy. This one is not.

  • Don’t forget to multiply by 1.0 to make this a float answer. The placement of where you put this 1.0 should be very strategic. Make sure you think about what part of this SELECT statement needs to be multiplied by 1.0!

I hope this helps someone!
