Answer 4

Time to go shopping!

Everything in the store has been discounted by 20%.

You are given a program that takes the price of an item as input. Complete the program so that it outputs the discounted price to the console.

Sample Input
100

Sample Output
80

//so we don’t overwhelm you, we’ve hidden the code that executes the input
function main() {
var oldPrice = parseInt(readLine(), 10)
var price = 100;
var discount = 20;
var newPrice = price - (price * discount) / 100;
console.log(newPrice);

I have three test case , Ive pass one but doesn't want to pass the exercise

Answer 5

Hi,

this code will pass all 4 tests

var oldPrice = parseInt(readLine(), 10)

var Price = oldPrice*1
var Discount = 20
var newPrice = Price - (Discount * Price)/100
console.log(newPrice)

at least it worked for me ;)

Greetings!

Answer 6

You need it to transform the price into numeric data. Otherwise the system will come back with no numeric data on the tests.

Answer 7

why did you use: var Price = oldPrice*1

??

Answer 8

function main() {
var oldPrice = parseInt(readLine(), 10)
var Price = oldPrice*1
var Discount = 20
var newPrice = Price - (Discount * Price)/100
console.log(newPrice)

}
