Dime a Dozen Diamonds makes synthetic diamonds by treating carbon. Each diamond can be sold for $$120.$ The material cost of a standard diamond is $$60.$ The fixed costs incurred each year for factory upkeep and administrative expenses are $$204,000.$ The machinery costs $$1\mathrm{.}5$ million and is depreciated straight$-$line over $10$ years to a salvage value of zero.
