> Math Through the Decades:
>>
>> 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?
>>
>> Teaching Math in 2010:
>>
>> El hachero vende un camion carga por $100. La
>> cuesta de production es.............
