You can use Jquery to handle event dropdown list of number changing.

It look like: 

var $number = $("#number"); 
$number.on("change", function(){
         // do something here
});

And then, you assign value for price accordingly.

var number = parseInt($(this).val(), 10);

var priceAccordingTo = 0;
switch(number){
    case 1: priceAccordingTo = 4; break;
    case 2: priceAccordingTo = 5; break;
    case 3: priceAccordingTo = 14; break;
    }
$("#price").val(priceAccordingTo);

Here is the link for demo.
