Yes or No

His cost of production is $80 and his profit is
$20

Your assignment: Underline the number 20.


5. Teaching Math In 2000s

A logger cuts down a beautiful forest because he is selfish and
inconsiderate and cares nothing
for the habitat of animals or the
preservation of our woodlands.
He does this so he can make a profit of
$20. What do you think of this
way of making a living? Topic for
class participation after
answering the question: How did the birds
and squirrels feel as the logger
cut down their homes? (There are no
wrong answers, and if you feel
like crying, it's ok).
