Question: Now that the add_transaction method exists, make the add_transaction method append a hash to the @transactions array. The hash should have the keys description and amount, as symbols, and values that match the arguments to the method.

Code:

bank_account.rb 
class BankAccount
  attr_reader :name

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

  def add_transaction(description, amount)
    @transactions.append({"description" => description, "amount" => amount})
  end

end

hi Devin

First you need to change the hash in the add_transaction method so that the keys are symbols, not strings:

{:description => description, :amount => amount}

Also, I looked at the ruby docs and couldn't find an append method for Array, so you'll need to use the push method or the << operator:

@transactions.push({:description => description, :amount => amount})

or

@transactions << {:description => description, :amount => amount}
