To produce a manual, John has to write the text, after which Ann has to draw sketches and typeset the document. John can start with any section of the book (i.e., he does not have to start with Section 1). The work has to be done within 95 days. The network diagram below shows the precedence relationships and duration of each activity.

Draw a Gantt chart to show how the work can be done within 95 days.
Take into account that both John and Ann are able to attend to only one task at a time.7
