    Computers can be temperamental with entering test answers. Be sure you are using the correct decimal places. Maybe it said round the nearest hundredth?. Nearest tenth?. Be careful.

    My answer should only have to be to four decimal places, but my answer of 77.33666, rounded to 77.3367 by the program, is wrong. What are you getting?

    Thanks for the help, but this program is just hating on me. I can skip it it's no big deal.
