.25q+.10d=4.50
\n" ); document.write( "q=d+4
\n" ); document.write( ".25(d+4)+.10d=4.50
\n" ); document.write( ".25d+1+.10d=4.50
\n" ); document.write( ".35d=4.50-1
\n" ); document.write( ".35d=3.50
\n" ); document.write( "d=3.50/.35
\n" ); document.write( "d=10 number of dimes.
\n" ); document.write( "q=10+4=14 number of quarters.
\n" ); document.write( "Proof:
\n" ); document.write( ".25*14+.10*10=4.50
\n" ); document.write( "3.50+1.00=4.50
