Hello, I had a quiz last night and I missed some of the questions, I would like to understand them before my test. 1) Consider two investment opportunities, Investment A and Investment B. Investment A pays interest at the rate of 4% per year, compounded semi-annually. Investment B pays interest at the rate of 3.925% per year, compounded daily. Which investment provides the better return? 2)You borrowed some money at 8 percent per annum. You repay the loan by making three annual payments of $ 285 (first payment made at t = 1), followed by five annual payments of $ 540 , followed by four annual payments of $ 755 . How much did you borrow? (Round your answer to 2 decimal places; record your answer without commas and without a dollar sign). 3)Several years ago, Bill Smith borrowed $125,000 to buy his house. He has a 15 year, monthly payment mortgage with an interest rate of 8.75 percent per annum. Bill is thinking about refinancing his house so he would like to know the payoff on his current loan. Assuming that he just made payment number 69 , compute the payoff on Bill's loan. 4)I plan to deposit $ 334 into my retirement every year for the next 25 years. The first deposit will be made today (that is, at t = 0) and the last deposit will be made at the end of year 24 (that is, at t = 24). I plan to make no other deposits. Assuming that I will earn 12.16 % p.a. on my retirement funds, how much money will I have accumulated 36 years from today (that is, at t = 36) 5)Sam refuses to retire until his retirement account has a balance of at least $ 324,138 . Sam refuses to make any more deposits in the account. The account currently has a balance of $ 121,787 and earns 6% per year, compounded semi-annually. How long does Sam have before he will retire Thank you, if I can have explanations about these problems it will help me for the next test
