&gt; Last week I purchased a burger at Burger King for \$1.58. The counter

&gt; girl took my \$2 and I was digging for my change when I pulled 8 cents from

&gt; my pocket and gave it to her. She stood there, holding the nickel and 3

&gt; pennies, while looking at the screen on her register. I sensed her

&gt; discomfort and tried to tell her to just give me 2 quarters, but, but she

&gt; hailed the manager for help. While he tried to explain the transaction to

&gt; her, she stood there and cried.

&gt;

&gt; ************************

&gt;

&gt; A logger exchanges a set "L" of lumber for a set of "M" of

&gt; money. The cardinality of set "M" is 100. Each element is worth one

dollar.

&gt; Make 100 dots representing the elements of the set "M." The set "C," the

&gt; cost of production, contains 20 fewer points than set "M." Represent the

set

&gt; "C" as a subset of set "M."

&gt;

&gt; Answer this question: What is the cardinality of the set "P"

&gt; of profits?
