If you are allowed to use technology for this, go to an online boxplot generator such as the one at http://www.mathwarehouse.com/charts/box-and-whisker-plot-maker.php Crank out the first quartile and I'll tell you if I got what you did. Okay?

The first quartile is 40. I think you got the third quartile. See attachment.
