Financial Questions (Part 2)...need istance.?

Far better to consult your textbook, fellow clmates, or even teacher rather than try to get answers to your homework here. For one thing, you're more likely to fulfill the purpose of education - learning - by figuring out and/or discussing how to arrive at the solution instead of getting somebody to just tell you the answer. On top of that, why would you trust an unknown person who is not studying the material you are to give you the correct answer? Too likely they will give you wrong answer.
