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:
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

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}
