5.26 An industrial engineer is considering two robots for purchase by a fiber-optic manufacturing com- pany. Robot X will have a first cost of $80,000, an annual maintenance and operation (M&O) cost of S30,000, and a $40,000 salvage value. Robot Y will have a first cost of $97,000, an annual M&O cost of $27,000, and a $50,000 salvage value. Which should be selected on the basis of a future worth comparison at an interest rate of 15% per year? Use a 3-year study period.

A forty-foot wooden hull fishing vessel sprang an unexpected leak a few days after leaving port. As more water entered the vessel, the engine was flooded, and the vessel eventually sank. Inspection of the vessel during the leak showed that the water was coming from underneath a refrigerated space in the front part of the vessel. In view of its construction style, the bilge underneath the vessel was inaccessible. The underwriter refused to indemnify the insured for the loss of the vessel by claiming that the latter had not exercised diligence to make the vessel seaworthy prior to the developing of the leak. The owner/master of the ship had no knowledge of the leak before the ship started its voyage. Do you think the loss is covered under the policy?
