Scenario Cartech Manufacturing is engaged in the production of replacement parts for automobiles. One plant specializes in the production of two parts: Part 271 and Part 342. Part 271 produces the highest volume of activity, and for many years it was the only part produced by the plant. Five years ago, Part 342 was added. Part 342 was more difficult to manufacture and required special tooling and setups. Profits increased for the first three years after the addition of the...
