I did explain it, Mary. We already know that you have a 70 and 100. There has to be at least 82's since it's the mode (occurs the most). We can then solve for the missing number. (70+82+82+100+x)/5=76..x will be the last missing number.
*October 11, 2010*

70+82+82+100+x/5=76 (There has to be at least two 82's since it is the mode.) Solve for x, and that's the third unknown.
