Tanner hires Andrea under a written contract to purchase antiques for him. Andrea's friend Carley is an antique dealer and agrees in writing to sell a set of Louis XIV chairs for $$5800.$ Although Andrea could have purchased similar chairs elsewhere for under $$5000,$ she decides to purchase the chairs from her friend. Andrea signs as an agent of Tanner. Tanner gives Andrea the cash for the purchase, but Andrea decides to use $$1000$ to pay some of her own bills and transfers the other $$4800$ to Carley. Carley sends an invoice to Elliot for the balance of $$1000.$ Does Tanner have to pay that balance?
