Mathematics - then and now in Norway

• Mathematics in 1950
  A logger sells a carload of timber for NOK 1,000.
  The lumberjack's costs are 4/5 of the price.
  What does the lumberjack earn from the sale?
  
  
• Mathematics in 1960
  A logger sells a carload of timber for NOK 1,000.
  The lumberjack's costs are 4/5 of the price, or NOK 800.
  What does the lumberjack earn from the sale?
  
  
• Mathematics in 1970
  A logger trades a carload T (for timber)
  against a sum P (for money.) The base number for T is 100.
  Each item is worth a penny.
  Make 100 dots to represent the elements T. K (costs)
  contains 20 fewer than in the base number P.
  
  Derive K as a differentiable of P and answer the following questions:
  
  What is the base figure for F (profit)?
  
  
• Mathematics in 1980
  A logger sells a carload of timber for NOK 10,000.
  The lumberjack's costs are NOK 8,000 and the profit is NOK 2,000.
  Underline the number 2,000.
  
  
• Mathematics in 1990
  By cutting down the trees, the logger earns NOK 2,000.
  What do you think about this way of making a living?
  
  Investigate the following questions:
  How did the birds and animals of the forest react to the logger cutting down the trees.
  - There are no wrong answers.
  
  
• Mathematics in 2000
  A timber company outsources all its loggers.
  The average lumber worker in this company
  earned NOK 285,000 a year, had 3 weeks' holiday and all the usual social benefits.
  A hired logger's hourly price is NOK 500.
  
  Did it make sense for the company to outsource all the loggers?

Non Stop

Det begynner å bli en stund siden sist jeg koste meg med Non Stop.
Denne gangen var det Nons Stop i Påske Edition som skulle under lupen.
