Marco was a furniture buyer for Wellart Department Stores. Marco was authorized to enter into contracts worth up to $50,000. Marco entered into a contract with Frank's Furniture to purchase $100,000 worth of dining room furniture. If Wellart refuses to honor the contract and Frank's sues:

Frank's will win, as Marco had implied and/or apparent authority.

Explanation:

Frank's will win, as Marco had implied and/or apparent authority.

Express authority is the authority which the principal has expressly given to the agent whether in a written or orally form.

Implied authority ( it can as well be described as usual authority) is the authority of an agent to acts which are reasonably incidental to and necessary for the effective performance of his duties.

So relating the above to the situation at hand, Mark acted based on the authority given to him by Wellart Department Stores. It was an implied authority.
