آپدیت قیمت کل با Ajax

سلام دوستان.
من میخوام وقتی تعداد محصولات تغییر کرد، قیمت کل هم تغییر کنه:
کد blade:

@php $total = 0; @endphp
                @foreach($carts as $cart)
                <form action="">
                <div class="row clearfix">
                    <div class="item-block-1">
                        <div class="image-wrapper">
                            <div class="image">
                                <a href="{{ $cart->foods->path() }}"><img src="{{ $cart->foods->getImageUrl() }}" style="margin: -10px 0 0 0;" alt="" /></a>
                            </div>
                        </div>
                    </div>
                    <div class="product">
                        <h4><a href="{{ $cart->foods->path() }}">{{ $cart->foods->title }}</a></h4>
                    </div>
                    <input type="hidden" id="foods_id_{{ $cart->foods_id }}" value="{{ $cart->foods_id }}">
                    <div class="quantity">
                        <select id="food_quantity_{{ $cart->foods_id }}" onchange="update({{ $cart->foods_id }})">
                            <option value="1" {{ $cart->quantity == '1' ? 'selected' : '' }}>1</option>
                            <option value="2" {{ $cart->quantity == '2' ? 'selected' : '' }}>2</option>
                            <option value="3" {{ $cart->quantity == '3' ? 'selected' : '' }}>3</option>
                            <option value="4" {{ $cart->quantity == '4' ? 'selected' : '' }}>4</option>
                            <option value="5" {{ $cart->quantity == '5' ? 'selected' : '' }}>5</option>
                            <option value="6" {{ $cart->quantity == '6' ? 'selected' : '' }}>6</option>
                            <option value="7" {{ $cart->quantity == '7' ? 'selected' : '' }}>7</option>
                            <option value="8" {{ $cart->quantity == '8' ? 'selected' : '' }}>8</option>
                            <option value="9" {{ $cart->quantity == '9' ? 'selected' : '' }}>9</option>
                            <option value="10" {{ $cart->quantity == '10' ? 'selected' : '' }}>10</option>
                        </select>
                    </div>
                    <div class="price" id="updatePrice_{{ $cart->foods_id }}">
                        {{ $cart->foods->price * $cart->quantity }}
                    </div>
                    <input type="hidden" id="price_id_{{ $cart->foods_id }}" value="{{ $cart->price }}">

                    <div class="delete">
                        <button type="submit"></button>
                    </div>
                </div>
                    @php $total += $cart->foods->price * $cart->quantity; @endphp
                @endforeach
                </form>
                <div class="row clearfix" style="float: left">
                    <div class="total">
                        <label style="font-size: 18px">
                            قیمت کل:
                        </label>
                        <p>{{ $total }}</p>
                    </div>
                </div>

کد ajax:

$.ajaxSetup({
                headers:{
                    'X-CSRF-TOKEN': $('meta[name="csrf-token"]').attr('content'),
                }
            });
            function update(foodId) {
                var quantity = $('#food_quantity_'+foodId).val();
                var price = $('#price_id_'+foodId).val();
                $.ajax({
                    type: "POST",
                    dataType:"json",
                    data: {foods_id:foodId, quantity:quantity, price:price},
                    url: "/edit",
                    success: function (data) {
                        document.getElementById('updatePrice_'+foodId).innerHTML = price * quantity;
                        const Msg = Swal.mixin({
                            toast: true,
                            position: 'top-end',
                            icon: 'success',
                            showConfirmButton: false,
                            timer: 3000
                        });
                        Msg.fire({
                            type: 'success',
                            title: data.status,
                        });
                    },
                })
            }
