I have no idea what you're asking here but it made me laugh!! — Max Paymar, Feb 24 '17 at 18:49
Basically you want the sum of these numbers? Please provide some code and better explanation. — Armin, Feb 24 '17 at 18:50
If you want to _loop_ over something, then start with an array or object that holds the data, not individual variables. — CBroe, Feb 24 '17 at 18:50

There's nothing to loop over here. You've defined each person as a separate variable.

Consider changing your data structure:

let people = [
  { name: 'Keith', amount: 18 },
  { name: 'austin', amount: 4.5 },
  // etc. etc.
];

From there you can use something like this:

let total = 0;
people.forEach((person) => {
  total += person.amount;
});
console.log(total);

Once you have that mastered, look into map and reduce.

Also, be very careful with currency. Don't get bit by floating point rounding. How can I format numbers as money in JavaScript?

@Smit Of course I do. What's there to try with the code in the question? This person has no idea what they're doing. A little help at the beginning can get them moving. You should also note that I included some links for further reading. – Brad Feb 24 '17 at 18:54
As @Brad mentions please be very careful with floating point rounding. You may wish to round the `person.amount` before running the calculation or at least rounding it at the end. – Nicholas Koskowski Feb 24 '17 at 18:54
