Let number of quarters = q
\n" ); document.write( "Therefore number of dimes = 55 - q\r
\n" ); document.write( "\n" ); document.write( "By condition, q * 25 + (55 - q) * 10 = 850 [all converted to cents]
\n" ); document.write( "25q + 550 - 10q = 850
\n" ); document.write( "25q - 10q = 850 - 550
\n" ); document.write( "15q = 300
\n" ); document.write( "q = 300/15 = 20\r
\n" ); document.write( "\n" ); document.write( "Therefore, number of quarters = 20
\n" ); document.write( "and number of dimes = 55 - 20 = 35
\n" ); document.write( "
\n" );
