javascript – Calculating tier price

This is the example data:

100 items or less = $20
200 items or less = $15
500 items or less = $10

Example scenario:

user inputs 150 items -> price is $15 per item

And this is how far I get:

http://jsfiddle.net/ByPh5/

<script type=\"text/javascript\">

$(function(){

var tier_prices = {
    \'100\':\'20\',
    \'200\':\'15\',
    \'500\':\'10\'
}

var user_input = $(\'#user_input\').val();

var price_output = 0;                    
/*
   calculate
*/

    $(\'#price_output\').text(price_output)


})​

</script>

<input type=\"text\" id=\"user_input\" value=\"150\"/>
<p id=\"price_output\"></p>​

any help is much appreciated
