The management of the Conway Corporation is considering five alternative new-product proposals that their employees have submitted to them:
\begin{matrix} \text{Proposal} & \text{Rate of Return} \\ \text{Fryer} & 49\% \\ \text{Box Loader} & 26\% \\ \text{Conveyor} & 19.5\% \\ \text{Planer} & 23\% \\ \text{Cutter-Loader} & 26.5\% \end{matrix}Conway currently enjoys an average return of 260h on total investment. Which proposal(s) is (are) acceptable?
Using the current average return on total investment as the MARR, only Fryer and Cutter-Loader are strictly acceptable. If the rule is: ROR ≥ MARR, then Box Loader is also acceptable.
