Epsilon currently pays $86 per unit to buy a port for a product it sells. Epsilon hos excess capacity, and estimates that making the part would incut variable costs of $8 for direct materials and $50 for direct lobor. Epsilon's normal predetermined overhead rate is 150% of direct labor cost, but management computes an incremental overhead rate of $20.00 per unit to make this part. Epsilon should choose to: Multiple Choice Buy since the relevant cost to make it is $94 per unit O Make since the relevant cost to make it ls $78,00 per unit. O Buy since the relevant cost to make it is more than $86.00 per unit. Make since the relevant cost to buy is $106.00 per unit. O Buy since the relevant cost to make x ls $114.00 per unit
