each of which requires an up$-$front expenditure of $$7\mathrm{.}5$ million. The expected net cash

b$.$ What is the NPV for each project using a cost of capital of $12\%?$

c$.$ At the $12\%$ cost of capital rate, which project$($s$)$ should be accepted and why?

d$.$ At the $17\%$ cost of capital rate, which project$($s$)$ should be accepted and why?
