You know the old trope "You must pay the rent!" "I can't pay the rent!"? I'm experiencing it right now with schoolwork: "You must grade the papers!" "I can't grade the papers!" Now I just need a dashing young man to burst into my room and cry, "I'LL grade the papers!"

Any volunteers? No? Bueller?

Her puppet jewelry is also very cool.

Unless I'm talking about needing a Gother Than Thou showstopper outfit.

Something in pink and black, I hope.

Something in pink and black, I hope.

I hope so, too. I'm waiting to hear back from my One True Seamstress about if she has the time to make me a black-with-pink-trim Polonaise.

there's too much going on right now to relax and enjoy it.

Hrm. You sure? Well, the offer's open, because I know I won't get off my ass and go this year.

Jilli, I need you to come down and go through my closet with me, and then we can go shopping!

Something in pink and black, I hope.

Oh, that would be SO MUCH FUN.

Yay! Math watch-n-post!

We are such geeks.

I can't picture Jilli not being a show stopper.

Hec, pretty jewellery links.

I had a dentist appointment today. Two cavities that have to be filled next week. Then I went shopping with Mom. I didn't spend that much because it was almost all exchanges and gift certificate spending, but I did score a satin skirt at Banana Republic for a party Saturday night. I wasn't going to get it because it was marked at $68, but it was only $22.

Sorry about the fillings, sj. I had four last week, so I have a lot of empathy. But YAY skirt!

Ok. Math Problem 1.

On August 13, 2001, you could buy $10,000 US Treasurey bonds that pay simple interest of

• 5.51% per year in February each year through maturity in February 2031, at a cost of $9,802 each; or

• 11.25% per year in February each year through 2015, at a cost of $15,529 each.

Each bond also returns $10,000 at maturity.

a) What is the annual yield of each investment?

b) Compare these two investment opportunities, which differ vastly in interest rate but also in cost.

Here are the notes I took down when we discussed this problem in class:

• You buy a bond for a certain amount of money. Ex: $9,802.

• Every year you earn simple interest on the face value of the bond. Ex: 5.51% on $10,000 - paid to you each year.

• So, in 2001 you pay $9,802; every year you get $551. In 2031 you get $10,000. So, total amount: 551x30+10,000.

Part B)

• You pay $15,529 to buy a bond with a face value of $10,000; 11.25% interest; 15-year term

• Annual Yield = total interest/your principal
