a) Bozo owes $4000 due in one year and $8,000 due in six years. Unfortunately, Bozo is unable to meet the $4000 obligation. By mutual consent with the lender, Bozo is allowed to pay off both loans after 4 years at 8% monthly. How much does Bozo pay?

b) Bozo borrowed $10,000 from Ernie due in 4 years at 6% compounded monthly. Immediately after the debt is contracted, Ernie sells the note to Max for an amount based on 5% compounded monthly. How much does Ernie receive?

c) Max needs to buy a refrigerator. The refrigerator Max wants requires a down payment of $2000. The refrigerator is purchased on time, with Max planning to pay $2000 at the end of one year and $4000 at the end of 4 years. What is the cash price of the refrigerator if the interest rate is 10% compounded monthly? (Cash = Now)

* If it is alright with someone, can you please assist me with each part here? I am having trouble trying to understand on how to go about figuring each part out. All of these parts count as one problem, so I would really appreciate the help. Thanks!
