Management also considered, but rejected, the alternative of dropping product P50 and not replacing the old appliance. If that were done, the $275,000 invested in the new appliance could instead have been invested in a project that would have returned a total of $378,000. Required: acquired 1.

What is the total sunk cost regarding the decision to buy the model 300 rather than the model 400 ? 3. What is the total opportunity cost regarding the decision to invest in the model 300 ?
