“A logger cuts and sells a truck load of lumber for $100. His cost of production is four-fiths of that amount.
What is his profit?”

What is the cardinality of set P of profits?”
80’s education reform version:
“A logger cuts and sells a truckload of lumber for $100. His cost is $80, and his profit is $20.
Find and circle the number 20.”

Спасибо. Появилась оригинальная мысль, но она потребует частичной реорганизации старой идеи, займусь скором будущем. Естественно результатами поделюсь с читателями блога!
