Hahn Manufacturing purchases a key component of one of its products from a local supplier. The current purchase price is $$1,400$ per unit. Efforts to standardize parts succeeded to the point that this same component can now be used in five different products. Annual component usage should increase from $150$ to $700$ units. Management wonders whether it is time to make the component in$-$house, rather than to continue buying it from the supplier. Fixed costs would increase by about $$25,000$ per year for the new equipment and tooling needed. The cost of raw materials and variable overhead would be about $$1,000$ per unit, and labor costs would be $$350$ per unit produced.

a$.$ Should Hahn make rather than buy?

Hahn should the components, saving $ per year as compared to the other decision. $($Enter your response rounded to the nearest whole number.$)$
