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 I wanted to point out the evolution in teaching math since the 1950s:
Q. A logger sells a truckload of lumber for $100. His cost of production is 4/5 of the price. What is his profit ?
Q. A logger sells a truckload of lumber for $100. His cost of production is 4/5 of the price, or $80. What is his profit?

Q. 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.
Q. 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.)
