Problem 2-8

A retail store had sales of $45,000 in April and $56,000 in May. The store employs eight fulltime workers who work a 40-hour week. In April the store also had seven part-time workers at 10 hours per week, and in May the store had nine part-timers at 15 hours per week (assume four weeks in each month).|

Required:|
Using sales dollars as the measure of output, what is the percentage change in productivity from April to May? (Round your answer to 2 decimal places. Omit the "%" sign in your response.)|  
  Percentage change in productivity| 6.67  %  |
