Need Help! " undefined local variable or method `item"

I am creating a ShoppingCart class , when the shopping cart is filled with 5 or more items it takes a 10 percent discount. I am having trouble on the prints_cart method of class.


class ShoppingCart attr_reader :name

def initialize(name)
    @name = name 
    @items = []
end

def add_items(item)
    @items.push(item)
end   

def total
    total = 0.0
    @items.each do |item|
        total += item.price 
    end
    if @items.length < 5
    return total
else @items.length >= 5 
    return total - (total * 0.10)
end
end

def to_s 
    "Name: #{name}, Total: #{sprintf("%0.2f", total)}"
end

def print_cart
    puts "#{name}'s Shopping Cart"
    puts "-" * 40

    puts "Item".ljust(30) + "Price".rjust(10)
    add_items(item).each do |item|
        puts add_items.name.ljust(30) + sprintf("%0.2f", add_items.price).rjust(10)
    end

    puts "-" * 40
    puts "Total:".ljust(30) + sprintf("%0.2f", total).rjust(10)
    puts "-" * 40
end

end

class Items def initialize(name, price) @name = name @price = price end end

banana = Items.new("Banana", 10) orange_juice = Items.new("Orange Juice" , 10) rice = Items.new("Rice", 1) vacuum_cleaner = Items.new("Vacuum Cleaner", 150) anchovies = Items.new("Anchovies" , 2) shopping_cart = ShoppingCart.new("Joseph") shopping_cart.add_items(banana) shopping_cart.add_items(orange_juice) shopping_cart.add_items(rice) shopping_cart.add_items(vacuum_cleaner) shopping_cart.add_items(anchovies) shopping_cart.print_cart


ClassAssignment.rb:34:in print_cart': undefined local variable or methoditem' for #<ShoppingCart:0x007febe1153928> (NameError) from ClassAssignment.rb:63:in `<main>'
