Many printing presses are designed with large plates that print a fixed number of pages as a unit. Each unit is called a signature. A particular press prints signatures of 8 pages each. Suppose $C(p)$ is the cost of printing a book of $p$ pages, assuming each signature printed costs $0.16.

(a) What is the cost of printing a book of 64 pages? $
What if there are 65 pages? $
What if there are $p$ pages? $C(p) =$ $ where the cost is rounded (up/down) ? up down for the next signature.

(b) What are the domain and range of $C(p)$?
Domain: all nonnegative integer multiples of (1 through 16) ? 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16
Range:   all nonnegative integer multiples of (0.01 through 0.20) ? 0.01 0.02 0.03 0.04 0.05 0.06 0.07 0.08 0.09 0.10 0.11 0.12 0.13 0.14 0.15 0.16 0.17 0.18 0.19 0.20

(c) On a piece of paper, sketch a graph of $C(p)$.
