CASE 10-27 Plantwide versus Departmental Overhead Rates; Underapplied or Uverapplied Overhead [LO 10-3, LO 10-5, LO 10-6] Boyne University offers an extensive continuing education program in many cities throughout the state. For the convenience of its faculty and administrative staff and to save costs, the uni- versity operates a motor pool.

The motor pool furnishes gasoline, oil, and other supplies for its automobiles. A mechanic does routine maintenance and minor repairs. Major repairs are performed at a nearby commercial garage.
