formed a valid contract because Rachel's outward expressions showed the formation of a contract.

In contract, outward expressions refers to a situation when both parties has directly communicate the terms of a certain transaction and agreed upon it.
The contract is considered as 'valid' and considered to be a verbal agreement as soon as Rachel proposed a price and Julius agreed upon it.
One thing to remember, Even though this contract is considered as valid , it would be hard for Julius to held Rachel accountable to court since he has no way to proof that the verbal agreement has been made.
