I’m really digging up some old 3-acts now.
I just worked out Fry’s Bank Account using Microsoft Excel and noticed something odd.
At first I ran the numbers and got the same answer as the act 3 video. But I noticed that the money was not rounding off to the nearest cent every year. Wouldn’t banks do that? So I changed my formula to round it ever year and got a different answer (4.2 billion instead of 4.3). Which one is right?
I’m going to get to the bottom of this…at least before I do it in class.

Dan, I loved the simplicity of the pizza coupon activity. I think the idea of using coupons, or having kids come up with clever coupons is ripe for further exploration.
Thanks. I’ve always loved pizza problems in class and this will add a new dimension.

My students were admazed by the Fry’s Bank problem. My favorite part was when a student left out a zero and accidentally calculated the balance after 100 years. $8 after 100 years, but 4 billion dollars after 1,000 years. I had to try it on a different calculator to make sure that his calculator wasn’t broken.

I love the Fry’s Bank Account video. Just shared it with my Algebra I teachers, who are currently working through exponential growth models.

The “beep” reminds me of Jimmy Kimmel’s “this week in Unnecessary Censorship”. My bank just started doing colonic scans…..surprisingly refreshing…..

Well with respect to the Fry’s Bank question… He ought to be glad he doesn’t have his money in my bank. At 0.01% interest after 1000 years he would have a whopping $1.03. Even my credit union account at the grand rate of 0.4% for the money market account would land him a nice sum of only $50.37. Oh bring me back the good ol’ days when banks were required by law to have 5.25% Well maybe I don’t want the good ol’ days back, but I wouldn’t mind a nice solid interest rate right now.
