About eight years ago, Kicker faced the problem of rapidly increasing costs associated with work-place accidents. The costs included the following:
State unemployment insurance premiums ..........$100,000
Average cost per injury ................. $ 1,500
Number of injuries per year .............. 15
Number of serious injuries ............... 4
Number of workdays lost ................ 30
A safety program was implemented with the following features: hiring a safety director, new employee orientation, stretching required four times a day, and systematic monitoring of adherence to the program by directors and supervisors. A year later, the indicators were as follows:
State unemployment insurance premiums ........ $50,000
Average cost per injury ............... $ 50
Number of injuries per year ............... 10
Number of serious injuries ............... 0
Number of workdays lost .............. 0
Safety director’s starting salary ............. $60,000

Required:
1. Discuss the safety-related costs listed. Are they variable or fixed with respect to speakers sold? With respect to other independent variables (describe)?
2. Did the safety program pay for itself? Discuss your reasoning.
