Mark Papers employs 15 full-time employees and 10 trainees. Direct and indirect costs are applied on a professional labor-hour basis that includes both employee and trainee hours. Following is information for 2014:

                                                     Budget                 Actual
Indirect costs                                  $200,000             $300,000
Annual salary of each employee         $100,000             $110,000
Annual salary of each trainee             $25,000              $30,000
Total professional labor-hours           50,000   dlh         60,000   dlh

How much should a client be billed in a normal costing system when 500 professional labor-hours are used?
