what's wrong with this method

this seems right to me

bank_account.rb 
class BankAccount
  attr_reader :name

  def initialize(name)
    @name = name
    @transactions = []
    add_transaction("Beginning Balance", 0)
  end

  def debit(description, amount)
    add_transaction(description, -amount)
  end

  def credit(description, amount)
    add_transaction(description, amount)
  end

  def add_transaction(description, amount)
    @transactions.push(description: description, amount: amount)
  end

  def balance
    balance = 0.0
    @tansactions.each do|transaction|
      balance += transaction[:amount]
      end
    return balance
  end
end

Hi Elizabeth Tobin

You have everything correct, except for one spelling error.
In this line @tansactions.each do|transaction| you are missing an 'r' in @transactions. Once fixed up, the rest is great.

And just a quick note: In Ruby, you don't need the return keyword. Just having the variable name balance, Ruby will return the value.

Nice work! :) :dizzy:
