Just in case the link to my document didn't work, I am posting the answers here as well. Number 10 should be 5, not 50. Also, #25 could have been interpreted as 25*2 or a total of 25. Sorry for the confusion. On number 25, I had planned on using 25 as the total number of minutes for the two breaks, since it is completely unacceptable to spend 25 minutes on just one break!! However, as you see, I used it as per break in my expression! That's what I get for rushing!!
