You can put this solution on YOUR website!
Call the number of each q and d.
\n" ); document.write( "We have two equations:
\n" ); document.write( "25q + 10d = 960
\n" ); document.write( "and
\n" ); document.write( "d = 2q
\n" ); document.write( "This doesn't work out. I think you meant to say twice as many dimes as quarters...then your second equation becomes
\n" ); document.write( "q = 2d
\n" ); document.write( "
\n" );
