Stuck on this exercise. Error message says: Oops, try again. false and that's that. Console prints the total but still.


function StaffMember(name,discountPercent){
  this.name = name;
  this.discountPercent = discountPercent;
}

var sally = new StaffMember("Sally",5);
var bob = new StaffMember("Bob",10);

// Create yourself again as 'me' with a staff discount of 20%
var me = new StaffMember("Angelo", 20);

var cashRegister = {
  total:0,
  lastTransactionAmount: 0,
  add: function(itemCost){
  this.total += itemCost;
  this.lastTransactionAmount = itemCost;
  },
  scan: function(item,quantity){
  switch (item){
  case "eggs": this.add(0.98 * quantity); break;
  case "milk": this.add(1.23 * quantity); break;
  case "magazine": this.add(4.99 * quantity); break;
  case "chocolate": this.add(0.45 * quantity); break;
  }
  return true;
  },
  voidLastTransaction : function(){
  this.total -= this.lastTransactionAmount;
  this.lastTransactionAmount = 0;
  },
  // Create a new method applyStaffDiscount here
  applyStaffDiscount: function(employee){
  this.total = this.total * (employee.discountPercent / 100);
  }
  
};

cashRegister.scan('eggs',1);
cashRegister.scan('milk',1);
cashRegister.scan('magazine',3);
// Apply your staff discount by passing the 'me' object 
// to applyStaffDiscount
cashRegister.applyStaffDiscount(me);

// Show the total bill
console.log('Your bill is '+cashRegister.total.toFixed(2));

Heyyo, this is the section where you have a problem:

applyStaffDiscount: function(employee){
this.total = this.total * (employee.discountPercent / 100);
}


#3

To add on to what powell is saying, this is what your code translates to:
this.total = this.total * 20% (or .2).

So does the employee discount mean that you only pay 20% of the total? Or do you get 20% off of the total?

Special Note:
I calculated the problem a little differently and got a false answer as well, even though the total was right.
My logic was this: this.total * (100- employee.discountPercent)/100 = discount taken off
However, the "correct" logic is this.total -= this.total * employee.discountPercent/100. Could throw some people off.
