Let the number of \"5 by 7\" reprints be L
\n" );
document.write( "Then number of \"4 by 6\" reprints = 10 - L
\n" );
document.write( "Cost of \"5 by 7\" reprints: .75L
\n" );
document.write( "Cost of \"4 by 6\" reprints: .5(10 - L)
\n" );
document.write( "We then get: .75L + .5(10 - L) = 7
\n" );
document.write( ".75L + 5 - .5L = 7
\n" );
document.write( ".25L = 2
\n" );
document.write( "L, or number of \"5 by 7\" reprints =  <===== That's the LARGEST number, if she MUST get \"4 by 6\" also
\n" );
document.write( "You can do the check! \n" );

\n" );
