Prem Industry is considering making its own motor castings, which it currently purchases for ā¹ 20.50 per unit. This purchase price does not include the ordering, receiving, and inspection costs, which Prem estimates to be ā¹ 2 per unit. Prem feels that, it can manufacture the 6,500 required units at a lower cost than it pays by purchasing externally. The relevant costs for both the producing and buying alternatives are as follows:
