I am also getting this as incorrect and when I clicked onto 'show answer' it tells us that the correct answer is 49.76 which is what I added but it still marked it as incorrect
This is ridiculous. The answer tells us "(49.76 is the absolute number)" yet it is marked as incorrect. How is that teaching us anything. Very poor quality course!!.
@Admin - someone needs to sort this out.
I thought we were not supposed to discuss answers, but I put in that answer and it said wrong and then I spent a few hours trying to figure out what I did wrong and put in something else, which was of course wrong. Really tickes me.
If you go back to the question you should see that the number of attempts has been re-set to zero. You should now be able to re-post your answer to the question. I did it as soon as the email came out and it worked fine
