Borges Machine$$ Shop, Inc., has a$1-$year contract for the production of $75,000$ gear housings for a new$$ off$-$road vehicle. Owner Luis Borges hopes the contract will be extended and the volume increased next year. Borges has developed costs for three alternatives. They are$$ general$-$purpose equipment$($GPE$),$ flexible manufacturing system$($FMS$),$ and$$ expensive, but$$ efficient, dedicated machine$($DM$).$ The cost data$$ follow:
