W: Good morning, High Mountain Savings and Loan. How may we help you?
M: (13) Well, I’m looking for the highest rate possible on a short-term certificate to deposit an account.
W: Well, Let’s see what we can do for you. High Mountain is currently offering a rate of 6.4% on the thirteen-week account for the minimum deposit of only 12,000 dollars, 6.55% on the minimum deposit of 25,000 dollars and 6. 7% on a deposit of 50,000 dollars. Those will have yields of 6. 55% , 6. 71% and 6. 87% respectively.
M: Rate and yield? I’m afraid I don’t understand the difference.
W: Well, sir. The rate is the percentage of symbol interest paid on your money, and the yield is the total percentage you will receive on your account if you leave your money with us, frankly to say here, as the same interest rate.
M: Oh, well...eh...(14) But I’m not interested in long-term investing and three months sounds just fine.
W: Then perhaps you would like to open one of our high finance money market checking accounts. With the minimum balance of only 50,000 dollars, you’ll get interest of 6.1% on any amount over that, for a yearly yield of 6.27% . Of course, there is no penalty for early withdraw.
M: Er.. No, thank you. I...
W: (15) Or, could we persuade you to save with us if we offer you a dinning coupon book that will get you a 25% discount at many of the area’s leading restaurants and cost you only 12 dollars and 95 cents?
M: Look, I think I’ll just call around for more information. Thank you for your time.
