let x = total number of coins. Then x/5 = # of dimes, 2x/15 = # of nickels, and 2x/3 = # of pennies. Then
\n" ); document.write( "\"%28x%2F5%29%2A0.10+%2B+%282x%2F15%29%2A0.05+%2B+%282x%2F3%29%2A0.01+=+1.00\",
\n" ); document.write( "\"0.30x+%2B+0.10x+%2B+0.10x+=+15\", after multiplying both sides by 15.
\n" ); document.write( "\"0.50x+=+15\",
\n" ); document.write( "x = 30.
\n" ); document.write( "Thus there are 6 dimes, 4 nickels, and 20 pennies.
\n" ); document.write( "
\n" );
