During the midterm, the reviewing proctor notes in several cases the desk top surface was not clearly shown.  Show the camera both sides of your blank scratch paper and your notes page.  Then pick up your book and in view of the camera, place those two sheet in the book.  Then, again in view of the camera, place your calculator on top of the book. Put the book down, and then aim the camera at the work surface to verify no other materials or devices (such as a phone) are in the area. Click true after you have completed the above instructions.   Failure to follow these instructions explicitly will result in a grade of ZERO on the exam.

In the spider plot from the previous problem, if the annual savings were $2,200 and all other cost elements were held constant, the present worth would be approximately

This is a 3 point question.  Canvas will not let me put in extra credit so if you got this correct I will manually add the points when I review these.   Use present worth to calculate the benefit/cost ratio at i=5% for a highway project.  The first cost is $140K and O&M costs are $5K per year.  There is no salvage value after 20 years.  Time savings to users are worth $35K per year, and neighborhood disruption is a dis-benefit of $10K per year.

A spider diagram depicted was developed to analyze a project.  The base case for the project was:  Initial Cost                  Annual Savings           Salvage value              Project Life      10,000                      :  $2000,                        $1000                         8 years From the diagram, which cash flow element has the least effect on the present worth?
