In his backyard, Robert is erecting a new fence. What he will accomplish and how long it will take are described below: The fence design takes a day, and work may begin right away. After he has designed the fence, he can give each of his two pals (John and Bill) a day to buy and transport various supplies. While John just needs one day, Bill needs two days to procure and deliver his list of supplies. After John purchases and provides his list of items, the drilling of the post holes may begin. After the new holes are drilled and Bill delivers his list of materials, the process of setting the posts in concrete can begin. This process takes one day. Setting the posts in concrete takes one day and can start after the new holes are drilled and after Bill delivers his list of materials. Building and installing the panels and gate takes one day and can start after the poles are set in concrete. After the panels and gate are installed, it takes one day for Bill and John to clean up their mess, and they start after the gate is installed. At the same time, Robert begins painting the fence. He is done after three days, and the job is completed. Instructions: 1.
