A manufacturer is considering whether to make or buy a component used in its production. The annual cost of producing the 10 000 parts is as follows.

Direct variable manufacturing costs $ 300 000 Direct fixed manufacturing costs $ 100 000 Allocated overhead $ 50 000

If the manufacture buys the component, the direct fixed manufacturing costs can be reduced by 43 per cent. What is the maximum unit purchasing price that makes purchasing a beneficial decision in comparison to making?
