Here are the expected cash flows of the projects your firm is considering:

Project $012345$

A $($$$200,000)$ $$60,000$ $$70,000$ $$95,000$ $$75,000$ $$50,000$

B $($$$400,000)$ $$90,000$ $$120,000$ $$140,000$ $$165,000$ $$170,000$

C $($$$600,000)$ $$160,000$ $$190,000$ $$200,000$ $$190,000$ $$180,000$

D $($$$100,000)$ $$35,000$ $$40,000$ $$30,000$ $$35,000$ $$30,000$

E $($$$500,000)$ $$200,000$ $$180,000$ $$150,000$ $$130,000$ $$90,000$

F $($$$300,000)$ $$90,000$ $$100,000$ $$120,000$ $$90,000$ $$55,000$

Also, your firm$$s WACC $($which is a proper discount rate for each project$)$ is $8\mathrm{.}80\%$ pa$.$

a$.(10$ Points$)$ If you have $$1$M to invest and projects are not scalable, what will you invest in$?$

Please show three project combinations including the best one.

b$.(10$ Points$)$ If you could scale each project from $1$X to $4$X $($e$.$g$.,$ investing $2$X into project A

means all cash flows of project A get multiplied by $2),$ what would be your best project

combination? Please show the best and two alternative project combinations$$ NPV and PI to

prove your point.
