You may use jQuery for that purpose

$("#mymodalrooms").on("change",function(){

    if($("#mymodalrooms").val()==="3"){

        $("#totalamount").val(parseInt($("#totalamount").val())+10);

    }

});

Add jquery to add value in amount. You can use on change event for this.

$(document).on('change', '#mymodalnationality, #mymodalrooms, #mymodaladult, #mymodalchildren, #mymodalchildrenage', function(){

      var amount = $('#totalamount').val();

      amount = parseInt(amount) + 10;

      $('#totalamount').val(amount);

   });
