<PRE><B>Question 1128086</B>
&lt;br&gt;
This is a comment for new tutor @Mtrkcrc....  I hope he sees it.&lt;br&gt;
I see you have answered 6 questions from readers.&lt;br&gt;
I can see from your answers that you know how to answer the questions.  However...&lt;br&gt;
(1) In 3 of the 6 problems, you didn&#39;t answer the question; you either answered a completely different question by not using some of the given information, or you used numbers that were different from what was given.&lt;br&gt;
(2) In 2 of the other 3 problems, your answers were valid, and correct.  But they were probably of little use to the reader, because they were too short, with little or no explanation of WHY you were solving the problems the way you did.  Remember that the reader probably has far less knowledge of math than you do; take the time to EXPLAIN the solution process.&lt;br&gt;
(3) Finally, learn to use the { } symbols to show your calculations.  The calculation&lt;br&gt;
4950 plus 100 equals 5050&lt;br&gt;
is not as easy to read as if you used math symbols and enclosed it in the sets of curly brackets:&lt;br&gt;
{{{4950+100 = 5050}}}&lt;br&gt;
Continue to enjoy helping others learn math; but remember that you are almost certainly talking to someone who knows far less than you about the math.</PRE>
