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 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:
