More Change we don't need, Hope it ends soon!

I always have friends I can rely on for a good laugh, or is it a cry? In my job I constantly look at math problems, ROI analysis, cost structures, profitability, etc. So here's a math lesson:

Last week I purchased a burger at Burger King for $1.58 The counter girl took my $2 and I was digging for my change when I pulled 8 cents from my pocket and gave it to her. She stood there, holding the nickel and 3 pennies, while looking at the screen on her register. I sensed her discomfort and tried to tell her to just give me two quarters , but she hailed the manager for help. While he tried to explain the transaction to her, she stood there and cried. Why do I tell you this? Because of the evolution in teaching math since the 1950s:

1. Teaching Math In 1950s

A logger sells a truckload of lumber for $100. His cost of production is 4/5 of the price. What is his profit ?

2 Teaching Math In 1960s

3 Teaching Math In 1970s

4 Teaching Math In 1980s

A logger sells a truckload of lumber for $100 His cost of production is $80 and his profit is $20. Your assignment: Underline the number 20.

5 Teaching Math In 1990s

A logger cuts down a beautiful forest because he is selfish and inconsiderate and cares nothing for the habitat of animals or the preservation of our woodlands. He does this so he can make a profit of $20.. What do you think of this way of making a living? Topic for class participation after answering the question: How did the birds and squirrels feel as the logger cut down their homes? (There are no wrong answers, and if you feel like crying, it's ok. )

Who cares, just steal the lumber from your rich neighbor's property, he won't have a gun to stop you!
