counterexample.
One way to show that a statement is NOT a good definition
is to find a counterexample. In description, counterexample is an exception to
a “proposed general rule or law”. Philosophically, counterexample somehow
generalizes a set of ideas or a notion declared in its position. For example,
all colors are white. Therefore it is wrong to say that red, orange, blue or
any other “color” is not a color by which the statement declared itself.
Moreover, in mathematics counterexamples are utilized frequently
to testify theorems' limitations.
There are 3 working weeks and each work week she earns
$1250, so the total earning is:
total = 1250 * 3 = $3750
For each day of late, she is fined $100, and she must make
at least $3,000. So she can only be late for 7 days so that her earning would
be:
earning = 3750 – 7*100 = $3050
<span>Max number of days late = 7days</span>
