An automated stamping machine has been developed that can efficiently produce body frames, hoods, and doors to the desired scale. If the machine is leased, fixed expenses will increase by $58,000 per year. The firm’s production capacity will increase, which is expected to result in a 25% increase in sales volume. It is also estimated that labor costs of $33 per unit could be saved because less polishing and finishing time will be required.
