1. The Brugger corporation owned a farm, operated by Jason Weimer, who acted as the company's business agent. Tri-cycle, inc., was a farm equipment company. On behalf of brugger, Weimer offered to buy from Tri-cycle certain equipment for use on the farm. Tri-cycle accepted the offer, usinga pre-printed form. The form included a finance charge for the late payment. Weimer's offer had said nothing about finance charges, but he made no objection to the new term. Tri-cycle supplied the farm equipment but later alleged that brugger had refused to pay the $12,000 worth of supplies. Tri-cycle sued. In deciding whether tri-cycle was entitled to finance charges, the court inquired whether brugger, Weimer, and tri-cycle were merchants. Why did it look into that issue? Were they merchants?
