Calculating NPV and IRR

Businesses use NPV and IRR to determine whether a project will add$-$value for shareholders. After watching the CFA Level I Corporate Finance video, answer the following questions.

$$ According to the video, how should a company use NPV and IRR to decide whether a project should be undertaken?

$$ In the video, Trim Corp. is considering a project that is expected to have cash inflows of $$350,$ $$250,$ and $$150$ in years $1,2,$ and $3,$ respectively. What do you think would happen to the NPV of the project if the company expected the same cash flows, but in reverse order? In other words, what do you think would happen to the NPV of the $$150$ were the cash inflow in year $1,$ $$250$ were the cash inflow for year $2,$ and $$350$ were the cash inflow for year $3?$ Using the same discount rate as in the video, $25\%,$ calculate the NPV for the project with this string of cash outflows.
