4. Teaching Math In 1980s

I must say that we have a decent math department here where I work. Teachers are top notch, for the most part, and stay here, in this crap district, because they care about the students. I am sure that any of them could go to any other school, make more $$ and have fewer headaches.

I'm trying to get out as fast as I can... :help:

Remember to show all your step, remember your positves and negatives, the right answer will only give you .5 out of 5
x/100=4/5
4(100) / 5x
400/5x
x=400/5
x=80
100-80= 20
$20.00 is the loggers profit

1986 was a long time a go...i'm sure i missed a step but this is how our class would have answered the question for 5 marks. The correct answer was only worth 1/2 a mark though. The steps were worth more to prove you understood the point

6. Teaching Math In 2009

A logger sells a truckload of lumber for $100. His cost of production is $80 and his profit is $20. He invests his entire profit into General Motors common stock.

Class discussion: Is the logger an idiot or an unfortunate individual, caught in a global economic terror, who needs to be bailed out to cover his investment loss and cost of production? :cowboy:
