The following activities are required to restore a car. First, workers must disassemble the entire car and tag and catalog the parts. Next, they must strip the paint from the body panels, rebuild the engine, rechrome the bumpers and trim, and reupholster the seats. Each activity begins once the car has been stripped. After the paint has been stripped from the body panels, workers can paint the panels and the car frame. After painting, they can reassemble the body. After the car has been reassembled, they can install the interior panels and new carpet. They can install the reupholstered seats once they have installed the carpet and interior panels. After the engine is rebuilt and the body has been reassembled, the engine can be installed. With the car body reassembled, workers can install the rechromed bumpers and trim. Given the following information, Duration (days) Activity A-Disassemble car & catalog parts B - Strip paint C-Paint D- Rebuild Engine E-Rechrome Bumper F-Reupholster seats G-Reassemble body H - Install carpet & interior panels I - Install seats & interior trim K - Install engine L - Install bumpers & trim TennwWNA a.
