Divison B has got an opportunity to purchase the goods externally at 25$/unit. Varaible Cost is 20$ Without including 1.5$ saving on internal transfers. What would be the reduction in the group profit if Division B takes to purchase from external supplier 10,000 units? could you please help with the same?
