Can someone please help me with this method challenge, the discount is not being calculated.

Question

function main() {
var prodID = readLine();
var price = parseInt(readLine(),10);
var discount = parseInt(readLine(),10);

var prod1= new Product(prodID, price);
console.log(prod1.prodID + " price: " + prod1.price);

prod1.changePrice(discount);
console.log(prod1.prodID + " new price: " + prod1.price);
}

function Product(prodID, price) {
this.prodID = prodID;
this.price = price;

this.changePrice = function(discount) {
//your code goes here
this.discount = discount;

return price - (discount * price);
}
}

Values for the first case are...

Price : 1700;

Discount : 15;

Answer 1

Challenge has been solved.

Here is the solution:

function main() {
var prodID = readLine();
var price = parseInt(readLine(),10);
var discount = parseInt(readLine(),10);

var prod1= new Product(prodID, price);
console.log(prod1.prodID + " price: " + prod1.price);

prod1.changePrice(discount);
console.log(prod1.prodID + " new price: " + prod1.price);
}

function Product(prodID, price) {
this.prodID = prodID;
this.price = price;

this.changePrice = function(discount) {
//your code goes here

this.discount = discount;
this.price = this.price - (this.discount/100 * this.price);
}
}

Try this in changePrice function

this.discount = discount;
this.price = this.price * ((100 - this.discount) / 100);

Answer 6

Same solution but maybe this is more neater :))

function main() {
var prodID = readLine();
var price = parseInt(readLine(),10);
var discount = parseInt(readLine(),10);

//call out
var prod1= new Product(prodID, price);
console.log(prod1.prodID + " price: " + prod1.price);

prod1.changePrice(discount);
console.log(prod1.prodID + " new price: " + prod1.price);
}

function Product(prodID, price) {
this.prodID = prodID;
this.price = price;

this.changePrice = function(discount) {
this.discount = discount ;
//your code goes here
this.discount = discount/100;
this.price = this.price -(this.discount * this.price)
}
}
