Due to increase in product demand, management needs to increase labor production hours by an estimated 270 hours. Any-Business currently has 30 production employees whose hourly wages varies from $7.50 - $8.50 per hour.
One production manager proposed implementing 9 hours of mandatory overtime for each employee, while another proposed adding 9 new hires who work 30 hours weekly.
