Hello, can someone help me with these finance practice problems? Thank You!

1 What is cash management and what are its major functions? 2 What are the key factors to consider when opening a banking account? 3 In general, how much of your annual income should you save in the form of liquid reserves? What portion of your investment portfolio should you keep in savings and other short-term investment vehicles? 4 Your parents are retired and have expressed concern about the really low-interest rates theyre earning on their savings. Theyve been approached by an advisor who says he has a sure-fire way to get them higher returns. What would you tell your parents about the low-interest-rate environment and how would you advise them to view the advisors new prospective investments?

5 Judith is an RN who earns $3,250 per month after taxes. She has been reviewing her savings strategies and current banking arrangements to determine if she should make any changes. She has a regular checking account that charges her a flat fee per month, writes an Average of 18 checks a month, and carries an average balance of $795 (although it has fallen below $750 during 3 months of the past year). Her only account is a money market account with a balance of $4,250. She tries to make a regular monthly deposit of $50-$100 into her money market account but has done so only about every other month. Of the many checking accounts Judiths bank offers, here are the three that best suit her needs: -regular checking per-item plan. Service charge of 43 per month plus 35 cents per check -regular checking, flat-fee plan (the one Judith currently has), monthly fee of $7 regardless of how many checks are written. With either of these regular checking accounts, she can avoid any charges by keeping a minimum daily balance of $750 -interest checking, monthly service charge of 7%, interest of 3% compounded daily. With a minimum balance of $1,500, the monthly charge is waived.

Judiths bank also offers CDs for a minimum deposit of $500, the current annual interest rates are 3.5% for 6 months, 3.75% for 1 year and 4% from 2 years. A) Calculate the annual cost of each of the 3 accounts, assuming that Judiths banking habits remain the same. Which plan would you recommend and why? B) Should Judith consider opening the interest checking account and increasing her minimum balance to at least $1500 to avoid service charges? Explain your answer. C) What other advice would you give Judith about her checking account and savings strategy?
