Required:
i)At what weekly sales would company A maximize its profits? What would be the profit or loss of company B if company A were able to supply a profit maximizing quantity of its product each week?
ii)At what level of weekly sales would company B maximize its profits?
iii)If the two companies merge into one, what would be the profit maximizing output per week and what would be the weekly profit?
