Question 1163383
.


Sorry,


in your post, this sentence


<pre>
    "The contribution to profit and fixed cost from the sale of each book is $6.25."
</pre>

does not make sense.



Double check with your source.


When you will find an error, fix it.


After that, you may re-post your request to the forum.


If you do, then PLEASE do not post it to me personally.



Have a nice day / evening / night / morning / afternoon . . .
