It needs to be more clear when you must round the numbers in this question - for instance, I use the average that I put in the answer box, and I get the wrong answer, despite having done all the steps as instructed.

This has frustrated me greatly as I have been stuck on this single section for two days and for my math course I must do all the sections in order.
