price depends on the selection of radio input

Now, your price is based on conditions.

So, the way to calculate is a little different. Translating your words, in JS code it’d be something like:

``````const adultTripPrice = isPrivate && isWithAtv ? 100 : isPrivate ? 10 : isWithAtv ? 50 : 5;
const childrenTripPrice = isPrivate && isWithAtv ? 50 : isPrivate ? 5 : isWithAtv ? 25 : 3;

const childrenPrice = children * (childrenTripPrice)
``````

• `isPrivate` and `isWithATV` then 100
• `isPrivate` (but not `isWithATV`) then 10
• `isWithATV` (but not `isPrivate`) then 50
• Not `isPrivate` neither `isWithATV` then 5.

And then multiplies that number for the number of Adults. (the same logic applies to Children)

The updated code would be like:

``````function calculateTotal() {
const privateChildrenPrice = 0;
const sharedChildrenPrice = 0;

const withAtvChildrenPrice = 80;

const noAtvPrice = 10;

const children = +document.querySelector('#children').value;

const isPrivate = document.getElementById('private').checked;
const isWithAtv = document.getElementById('withatv').checked;

const adultTripPrice = isPrivate && isWithAtv ? 100 : isPrivate ? 10 : isWithAtv ? 50 : 5;
const childrenTripPrice = isPrivate && isWithAtv ? 50 : isPrivate ? 5 : isWithAtv ? 25 : 3;
const childrenPrice = children * (childrenTripPrice)

}
function updateTotal() {
const total = calculateTotal();
console.log(total);
document.querySelector('#totalPrice').innerHTML = total;
}

function increaseCount(e, el) {
var input = el.previousElementSibling;
var value = parseInt(input.value, 10);
value = isNaN(value) ? 0 : value;
value++;
input.value = value;
updateTotal();
}

function decreaseCount(e, el) {
var input = el.nextElementSibling;
var value = parseInt(input.value, 10);
if (value > 1) {
value = isNaN(value) ? 0 : value;
value--;
input.value = value;
}
updateTotal();
}

function decreaseCount2(e, el) {
var input = el.nextElementSibling;
var value = parseInt(input.value, 10);
if (value > 0) {
value = isNaN(value) ? 0 : value;
value--;
input.value = value;
}
updateTotal();
}

var MainImg = document.getElementById('MainImg');
var smallimg = document.getElementsByClassName('small-img');

smallimg[0].onclick = function () {
MainImg.src = smallimg[0].src;
};
smallimg[1].onclick = function () {
MainImg.src = smallimg[1].src;
};
smallimg[2].onclick = function () {
MainImg.src = smallimg[2].src;
};
smallimg[3].onclick = function () {
MainImg.src = smallimg[3].src;
};``````
