Can someone teach me how to combine just the values of keys together to a total?

"""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""" attr_accessor :checkings, :snack, :drink, :balance, :name

def initialize(checkings, balance) @Checkings = checkings @balance = balance

end

def snack(food) total_items = {} puts "How much is #{food} " price = gets.chomp.to_i total_items[food] = price loop do puts "Wanna buy more food?(Yes/No)" answer = gets.chomp case answer when "Yes", "yes", "YES" puts "What other snack you wanna buy?" snack = gets.chomp puts "Im sorry i can't see the lable how much is that?" price = gets.chomp total_items[snack] = price.to_i when "No", "no", "NO" puts "These are the items you are buying." p "----------------------------------------------------" total_items.each_key {|key| puts "You bought #{key}"} p "----------------------------------------------------" puts "Averaging total #{total_items.values}" total_items.values.to_s total_items break end end end end

def reciept(items)
    p "Your total for #{name} is"
    items.value


ally_bank = Bank.new("Chase", 120)
ally_bank.snack("Chips")
"""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""'
What i wanna do in reciept  is factor in all the snacks that ally bought and add the total values of the items together.

Hard to read the code above your receipt method, but I would suggest

  1. turning the values of the hash into an array using the total_items.map method
  2. Using the inject method to sum the values from that array together.

Have a look at the enumerable course for help on this :)
