can you draw CPM node diagram with three activities using FS relationship and durations calculated int he first step. As it says in the "hint"

16. A manufacturing plant makes parts of a machine with a productivity of 10 parts/hour. A quality inspector then inspects and tests the parts. The quality inspector can inspect 5 parts an hour. Twenty parts are then used to assemble the machine which takes one hour. How long will it take to make, inspect and test 80 parts? Draw a CPM node diagram showing relationship among the three activities. Show how you can optimize the schedule. Assume 5 day work week and 8 hours work day. Use Hour as unit of time. (show detail calculation, use Microsoft Excel) Hint: Individually calculate hours to make 80 parts, inspect and test 80 parts, and assemble 80 parts. Draw CPM nodes with three activities using FS relationship and durations calculated in the first step. Do forward and backward pass calculation. Draw a new CPM network, this time consider whether you can you start \\( 2^{\\text {nd }} \\) and \\( 3^{\\text {td }} \\) activity earlier. Use lead and do forward and backward pass calculations
