Several internet-based companies that use open-source software for their day-to-day operations have increased their productivity by relying on volunteer contributions. This increase in productivity has led to higher overall profits, as the companies spend less revenue on salaries. Therefore, start-up internet companies should follow this model by hiring a small core staff and assigning the rest of the necessary work to volunteers in order to increase profits.
The argument above that internet companies will increase profits by hiring fewer full-time employees is based on which of the following assumptions?
A. Internet companies that use open-source software are better suited to function efficiently with only a small core staff than traditional companies.
B. The core staff at start-up internet companies can manage all essential tasks that cannot be performed by volunteers.
C. Full-time employees and volunteers will have different levels of access to most projects undertaken by the company.
D. Internet companies will hire more full-time employees as they become more profitable due to volunteer contributions.
E. Companies that rely on both full-time employees and volunteer labor increase their overall revenue per working hour.
