The Truth

[atma]

Ain't this the truth?

 

Teaching Math in 1950:

A logger sells a truckload of lumber for $100. His cost of

production is 4/5 of the price. What is his profit?

 

Teaching Math in 1960:

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?

 

Teaching Math in 1970:

A logger exchanges a set "L" of lumber for a Set "M" of money. The

cardinality of set "M" is 100. Each element is worth one dollar.

Make 100 dots representing the elements of the set "M." The set "C",

the cost of production contains 20 fewer points than set "M."

Represent the set "C" as a subset of set "M" and answer the

following question: What is the cardinality of the set "P" of

profits?

 

Teaching Math in 1980:

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.

 

Teaching Math in 1990:

By cutting down beautiful forest trees, the Logger makes $20. What

do you think of this way of making a living? Topic for class

participation after answering the question: How did the forest birds

and squirrels feel as the logger cut down the trees? There are no

wrong answers.

 

Teaching Math in 2000:

A logger sells a truckload of lumber for $100. His cost of

production is $120. How does Arthur Andersen determine that his

profit margin is $60
