What is the approximate estimated time for the 100th unit?Answer:a.Base Unit = 10 direct labor hours10/25=40%, F=1.2797 F*BU = 1.2397*10 labour hours = 12.39 direct labour hours for the 10th unit.1/10 = 10%, F= 1.7158 F*BU=1.7158*12.39 labour hours = 21.25 direct labour hours for theunit 1.2/10=20%, F= 1.4584 F*BU = 1.5458*12.39 labour hours=18.06 direct labour hours for the unit 2.The expected average for the first two units is 19.65 hours [(21.25+18.06)/2]b. PP = 110/10 = 1000%, F=.3058, F*BU=.3058*12.39 = 3.78 hours.c.90 percent learning curve10/25 = 40%, F=1.1494 F*BU=1.1494*10 labour hours = 11.49 direct labour hours for the 10th unit.1/10=10%, F=1.4191 F*BU=1.4191*11.49 labour hours=16.30 direct labour hours for the unit 1.2/10=20%, F=1.2772 F*BU=1.2772*11.49 labour hours=14.67 direct labour hours for the unit 2.
