Question

I am new to JS... What did I do wrong here? Thats problem 1 in JS course...

//so we don’t overwhelm you, we’ve hidden the code that executes the input
function main() {
var oldPrice = parseInt(readLine(), 10)
var newPrice = 20(oldPrice*20/oldPrice)oldPrice
console.log newPrice
// your code goes here

}

Answer 1

newPrice=oldPrice-oldPrice*20/100

console.log(newPrice)
