The Central Publishing Company is about to publish its first reference hook in managerial economics. It is now in the process of estimating costs. It expects to produce 10,000 copies during its first year. The following costs have been estimated to correspond to the expected copies.
a. Paper stock ................................... $8.000
b. Typesetting ...................................$15,000
c. Printing .......................................$50,000
d. Art (including graphs) ..................... $9,000
e. Editing .......................................$20,000
f. Reviews ..................................... $3,000
g. Promotion and advertising ................$12.000
h. Binding .....................................$22,000
i. Shipping .....................................$10,000
In addition to the preceding costs, it expects to pa) the authors a 13 percent royalty and its salespeople a 3 percent commission. These percentages will be based on the publisher's price of $48 per book.
Some of the preceding costs are fixed and others are variable. The average variable costs are expected to be constant. Although 10,000 copies is the projected volume, the book could sell anywhere between 0 and 20,000 copies.
Using the preceding data,
a. Write equations for total cost, average- total cost, average variable cost, and marginal cost.
b. Draw the cost curves for quantities from 0 to 20.000 (in intervals of 2,000).
