Let t = T-shirts, c = CDs, and b = books

\n" ); document.write( "\"t%2Bc%2Bb+=+10\" the number of items is 10
\n" ); document.write( "\"25t%2B10c%2B5b+=+105\" the total cost ($25 for a T-shirt, $10 for a CD, $5 for a book) is 105
\n" ); document.write( "\"t%2Bc+=+b\" the number of books is equal to the combined number of T-shirts and CDs

\n" ); document.write( "I'll let you solve the system of equations to find the answer to the problem.

\n" ); document.write( "Note that the first and last equations together immediately give you the number of books; then substituting that number into the first and second equations gives you a system you can solve to find t and c.
