His cost production is 4/5 of this price. What is his profit? 1970 (traditional) A logger sells a truckload of lumber for $100. His cost of production is 4/5 of this price, or in other words, $80. What is his profit? 1970 (New Math) A logger exchanges a set of L lumber for a set of M money. The cardinality of set M is 100 and each element is worth a dollar. Make a square array of 100 dots to represent the elements of set M. The set C of the cost of production contains 20 fewer elements than set M. Represent set C as a subset of set M and answer the following question: What is the cardinality of set P profits? 1980 A logger sells a truckload of lumber for $100. His cost of production is $80 and his profit is $20. Your assignment is to underline the number 20. 1990 (Outcome-based destreamed integrated Math) By cutting down beautiful forest treees, an environmentally ignorant logger makes a profit of $20. What do you think of this way of making a living? In your group, use role play to determine how the forest birds and squirrels feel.
