$$ A labor$-$intensive process has a fixed cost of $$338,000$ and a variable cost of $$143$ per unit. A capital$-$intensive $($automated$)$ process for the same product has a fixed cost of $$1,244,000$ and a variable cost of $$92\mathrm{.}50$ per unit. How many units must be produced and sold at $$197$ each for the automated process to be preferred to the labor$-$intensive process?
