Ken Hensley Enterprises, Inc., is a small recording studio in St. Louis. Rock bands use the studio to mix high-quality demo recordings distributed to talent agents. New clients are required to pay in advance for studio services. Bands with established credit are billed for studio services at the end of each month. Adjusting entries are performed on a monthly basis. An unadjusted trial balance dated December 31, year 1, follows. (Bear in mind that adjusting entries already have been made for the first 11 months of year 1, but not for December.)
