5.13 McLaughlin Services is on contract to Tuscany County, Florida. One of the McLaughlin engineers is evaluating alternatives that use a robotic, liquid- propelled “pig” to periodically inspect the interior of buried potable water pipes for leakage, corro- sion, weld strength, movement over time, and a variety of other parameters. Two equivalent robot instruments are available.
Robot Joeboy: P = $-85,000;
annual M&O costs = $-30,000; S = $40,000 Robot Watcheye: P = $-97,000;
annual M&O costs = $-27,000; S = $42,000
a. Select one using an AW comparison, i = 10% per year, and a 3-year study period.
b. If the first cost of Watcheye is somewhat nego- tiable, by how many dollars must it increase or decrease to make the two instruments equally at- tractive financially? Use the 3-year study period.
