Hi,

I'm using JavaScript and knows how to solve this problem, but I'm not familiar with these i/o methods that's being used. Can someone here guide me on the problem with my code? I'm still trying to get used to how this site works.

function processData(input, tips, taxes) {
//Enter your code here
var mealCost = input,
    tipPercent = tips,
    taxPercent = taxes,
    tip = mealCost * (tipPercent / 100),
    tax = mealCost * (taxPercent / 100),
    totalCost = Math.round(mealCost + tip + tax);

    return totalCost;
} 

process.stdout.write('The total meal cost is ' + processData(12, 20, 8) + ' dollars.');
process.stdout.write('The total meal cost is ' + processData(15.50, 15, 10) + ' dollars.');

process.stdin.resume();
process.stdin.setEncoding("ascii");
_input = "";
process.stdin.on("data", function (input) {
_input += input;
});

process.stdin.on("end", function () {
    processData(_input);
});
