Say you have this problem:

You want to sell a book with a $10 profit margin.
Estimate the costs of materials:
 1 ream = 500 sheets costing about $20);
 Plastic Coil Spiral Binder cost about $12 per dozen;
 One time cost of a binding machine of about $130;
 Ink cartridges cost about $100 per 5000 pages;
 One time Laser (b/w) Printer cost of about $500;
Wholesale discount price should be 30% less than retail.
   (i.e. for retailers, and distributors only)
Library discount price should be 10% less than retail.
A bulk-order discount of 10% is available for 10 or more copies.

Solve set up the problem for the user to input the (1) number of pages
of the book, and the desired (2) profit margin; and output the (1)
wholesale trade discount 30%, the (2) library/bulk discount of 10%,
and finally the needed (3) retail price to make the desired profit.

Can anyone solve the problem in a Demonstration Project for version 7
or >?
