Profit calculator

tanicos · Jul 16, 2008

hello

can anyone point me in the right direction? searched google but no luck
what i need:

a profit calculator to:
Ex: people can calculate their profit for selling stuff.
Number of people: 20
Number of dvds: 10
Number of books: 10

Total profit 12000$

now here is the math: when they add 10 dvds this will be multiplied with 32$
when they add 10 books it will be multiplied with 28$
so 32*10=320$+280$(10*28)=600$ * 20people=12000$

Can someone tell me?thanks

function calc() {

  var cost_dvd = 32;
  var cost_book = 28;

  document.getElementById('total').innerHTML = Math.floor(document.getElementById('people').value) * (Math.floor(document.getElementById('dvds').value) * cost_dvd + Math.floor(document.getElementById('books').value) * cost_book);
}
</script>

take out the onkeyup="calc();" from the 3 <input>s and add an <button onclick="calc();> and you SHOULD get the same result, except on button click.
