How many times have math teachers been asked “how will we use this in our real lives”? I would bet that the answer is “a lot”! I know that even I have asked that question when I was a young person. I have asked that question when I am helping students during study hall. And I have definitely asked that question when help my own children at home at night and I don’t know the answer. But in the last few days, I think many people are using math in many creative ways. I am sure that you are well aware of the economic crisis – and it is a very serious matter so please don’t think that I am taking it lightly – but the best part of this crisis (and possibly the only good part) is the fact that people are doing a lot math lately.
I got to thinking about the concept of budgeting. I was taught at a young age, and the idea was solidified in my high school accounting class, that if you don’t’ have the money coming in, then you can’t spend it! If you don’t have the collateral, then you can’t get a loan, because when you can’t pay, they take things away from you. Not just what you bought that you can’t pay for, but other things to make up for the loaned out money… If an individual were to overspend, they would bounce checks, they would eventually be cut off from their credit cards, their belongings would be repossessed, their paychecks garnished, and they could end up claiming bankruptcy. This all makes sense to me, that is how I lead my financial life. I have to; I have children who depend on me to keep our lifestyle going…
What were these businesses thinking? Could they have been thinking about the customers (or should I say families) that they were working with? How many families are in jeopardy now thanks to this situation? Then, I heard a morning radio DJ – David Fudge out of North Platte
Mix 97.1 – put it into a new perspective… “If every person in the United States were to help solve this problem by donating money from their own bank accounts to reach the $700 billion dollar amount, each PERSON (no matter their age) would have to give about $2293.17!” (Using the most current census to do these calculations.)
Later, as I walked by a class yesterday only to hear them talking about weights, measures, and conversions. (Gerry Swingle's classroom.) Not such a surprising thing to hear in a school. However, as I was working I could hear the students laughing, gasping and even sighing about the mathematical calculations they were making. The students were engaged and motivated to figure out the right answers. They were wondering how this economic crisis would affect their lives – and they found out. Here is what they were calculating:
• Mass of a one dollar bill = one gram
• If you have $700 billion one dollar bills = 700,000,000,000 grams
• To convert this weight to kilograms 700,000,000,000 grams x 1kg/1000 g = 700,000,000 kg
• To convert from kilograms to pounds (the American way) = 700,000,000 kg x 2.20 lbs/kg = 1,540,000,000 lbs.
• To convert from pounds to tons = 1,540,000,000 x 1 ton/2000 lbs = 770,000 tons
• The legal limit of weight on a semi truck traveling through the state of Nebraska is 40 tons. To convert from tons to number of semis needed to move that money = 770,000 t x 1 semi/40 tons = 19,250 semi loads
• Which means every family in Arnold pays 100 loads of money parked in front of their houses
If every person paid $2293.17 to help with this debt…
It’s an interesting thought… but here is the kicker: If every person would have to pay $2293.17 to help with this debt… Puts things in a little different perspective doesn’t it?
But, rest assured, if the government doesn't bail out the banking system, the national debt can be carried across Nebraska in 270,000 semi trucks - not counting the $700 billion mentioned earlier.
Maybe we should thank those businesses and banks for the impromptu math lessons that are occurring in thousands of households and classrooms across this country. Now, aren’t you glad you paid attention in math class?
