Let $\"C\"$ = total cost of making $\"x\"$ CDs
\n" ); document.write( "Let $\"I\"$ = total income from making $\"x\"$ CDs
\n" ); document.write( "given:
\n" ); document.write( " $\"C+=+6x+%2B+720\"$
\n" ); document.write( " $\"I+=+10x\"$
\n" ); document.write( "The problem is asking \"When does the income = cost?\"
\n" ); document.write( " $\"I+=+C\"$
\n" ); document.write( " $\"6x+%2B+720+=+10x\"$
\n" ); document.write( " $\"4x+=+720\"$
\n" ); document.write( " $\"x+=+180\"$
\n" ); document.write( "180 CDs must be sold to break even \n" ); document.write( "
