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 translates through the relationship S (sale) a set "L" of lumber for a set "M" of money. The cardinality of set "M" is 100. Each element's token value is described by a unity relationship with one dollar. Make 100 dots represent the elements of the set "M"which positively map to the set "C" the linear cost of production where set "C" 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 domain cardinality of the set "P" for profit in a fixed finite model?

Teaching Math in 1980:

A logger sells a truckload of lumber for $100. Her cost of production is $80 and her 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 1996:

By laying off 40% of its loggers, a company improves its stock price from $80 to $100. How much capital gain per share does the CEO make by exercising his stock options at a base purchase price of one dollar and a Fair Market Value $80? Assume capital gains are no longer taxed, because this encourages investment.

Teaching Math in 1997:

A company out-sources all of its logging operations. The firm saves on benefits, and when demand for its product is down, the logging work force can easily be downsized. The average logger employed by the company earned $50,000, had three weeks vacation, a nice retirement plan and medical insurance. The contracted logger charges $60 an hour. Was outsourcing a good move?

Teaching Math in 1998:

A laid-off logger with four kids at home and a ridiculous alimony from his first failed marriage comes into the logging company corporate offices and goes postal, wasting 16 executives and a couple of secretaries — and gets lucky when he nails a politician on the premises collecting his kickback for cutting stumpage fees and fudging international trade figures. Was outsourcing the loggers a good move for the company?

Teaching Math in 1999:

A laid-off logger serving time in Millhaven Federal Prison for blowing away several people is being trained as a COBOL programmer in order to work on Y2K projects. What is the probability that the automatic cell doors will open on their own as of 00:01, 01/01/00?

• BLIND ROBINS SMOKED OCEAN HERRING (Bar Food Products): Possibly the world's most bizarre prepackaged tavern snack. Interestingly, the product's titular robin isn't actually blind, he's blindfolded — the better, presumably, to avoid looking at these heavily salted herring strips, which look like giant slugs.

• KYLMAENEN REINDEER PATE (Kylmaenen Oy): This Finnish canned good may not be particularly tasty, but at least it answers the age-old question of why Rudolph was so eager for that safe, steady job on Santa's sleigh team — he didn't want to end up a cracker spread.

• TENGU CLAM JERKY (Tengu Co): Nothing you've ever consumed can prepare you for the horror that is clam jerky. Still, this product does score a sort of conceptual coup: If you're the sort who's always found raw clams too slimy and gelatinous for your taste, these dried, shriveled mollusks will help you dislike clams on a whole new level.

• MEETER'S KRAUT JUICE (Stokely USA): Yes, that's sauerkraut juice, which is even worse than it sounds. The taste and smell can be a bit, well, "harsh", but "KJ" is reputed by its fans to have certain medicinal benefits (as a source of vitamin C, cure for intestinal bugs, etc.), which adds up to a classic case of the cure being worse than the disease.

• GUYCAN CORNED MUTTON WITH JUICES ADDED (Bedessee Imports):The best thing about this Uruguayan canned good is the very pouty-looking sheep on the package label — he seems to be saying, "Go on, eat me already." The second- best thing is the presence of both "cooked mutton" and "mutton" in the ingredients listing, which would seem to have all the mutton bases covered.

• ARMOUR PORK BRAINS IN MILK GRAVY (Dial Corp): If you're really looking to clog up those arteries in a hurry, you'll be pleased to learn that a single serving of pork brains has 1,170% of our recommended daily cholesterol intake. All the more ingenious, then, that the label on this product helpfully features a recipe for brains and scrambled eggs.

• SWEET SUE CANNED WHOLE CHICKEN (Sweet Sue Kitchens, Inc): From its size (think growth-impaired Cornish hen) to its overall appearance (it's stewed in a quivering mass of aspic goop), this product may change forever your idea of what constitutes a chicken. Gives new meaning to the old line about meat "falling off the bone."

• MUSK LIFE SAVERS (Nestle Confectionery): You may think musk is a scent, but over in Australia, they think it's a candy flavor. A candy flavor that tastes disturbingly like raw meat, to be precise. But what did you expect from a country where everyone happily consumes Vegemite?
