Well origionally I apparently did not give enough information, I have
gotten many answers which included a formula to find the number myself.
Which in itself was enough to get me the answer I was looking for. 
But some mentioned just punching the numbers in the Marc program and it
will do it for me, but for the life of me I cannot find where to put the
numbers in question in the program. It is such a simple program to use I
can't believe that it is not in there.
Thanks to everyone that replied.
