Re: Writing Rules from Words

How many ounces are in a pound? If I said "that brick weighs 80 ounces", what would you do with "80" to express the weight of the brick in pounds? Once you decide what must be done, express that process in terms of P(z) and z.

I'll do a similar problem for you.

he number of dollars D(c) as a function of the number of cents c.

Following Loren's advice:

If I have 52 cents ---> I have 52/100 dollars

and

If I have 27 cents ---> I have 27/100 dollars

so

If I have c cents ---> I have c/100 dollars

then we can write

\(\displaystyle D(c) = \frac{c}{100}\)

Do your problem similar way.
