4 (Mandatory) (20 points) Rough N' Tough (RNT) manufactures outdoors accessories. Management is considering producing the poles for their tents rather than continuing to purchase from their current supplier. The supplier charges $60 per set of poles. The cost accounting team has estimated that RNT would incur the following costs if they were to produce the poles instead: $40 per set for direct materials, $10 per set for direct labor, $7 per set for variable overhead, and $20 per set f fixed overhead application. RNT currently has unused production capacity and manufacturing equipment that could be used to manufacture the poles. RNT has planned to sell 5,000 tents this year.
