PROBLEM $1$: Proj Risk Analysis

Parallon Business Solutions, a division of HCA that provides revenue cycle functions, is evaluating two different

computer systems for handling provider claims. There are no incremental revenues attached to the projects,

so the decision will be made on the basis of the present value of costs. Parallon's corporate cost of capital is $10$ percent.

Here are the net cash flow estimates in thousands of dollars:

a$.$ Assume initially that the systems both have average risk. Which one should be chosen?

b$.$ Assume that System $Y$ is judged to have high risk. Parallon accounts for differential risk by adjusting its

corporate cost of capital up or down by $2$ percentage points. Which system should be chosen? Please add explanation in Excel formula or another way.
