\n" ); document.write( "quarter = 25 cents, dime = 5 cents. Some number of quarters (a x 25 cents) added to some number of dimes ( b x 5 cents) = 715 cents.
\n" ); document.write( " 25a + 5b = 715 with a + b = 37
\n" ); document.write( "a + 36b = 205 cents. We need many more quarters.
\n" ); document.write( "20a + 17b = 585cents. More a's needed.
\n" ); document.write( "25a + 12b = 685cents. Getting closer.
\n" ); document.write( "27a + 10b = 725 cents. Slightly too many a's.
\n" ); document.write( "26a + 11b = 715.
\n" ); document.write( "
\n" );
