A publisher finds that the cost of preparing a book for printing and of making the plates is $5000. Each set of 1000 printed copies costs $1000. He can sell the books at $5 per copy. How many copies must he sell to at least recover his costs?

**The string**:

S_{7}P_{5}A_{51} (Physical Change).
**The math**:

Pj Problem of Interest is of type *change*. Problems of profit, loss and growth are *change problems*. A break-even problem is a case where cost equals revenue (zero profit-zero loss). So, it can be viewed as of type *equilibrium problems* (in essence a *no-change* state). However, it is better to align it with the concept of profit, loss and growth of the marketplace. Where *profit* and *growth* are positive changes and a *loss* is a negative change.

Let *x* be the number of copies the publisher must sell to at least recover its cost;

Then cost of publishing x copies = 5000 + x

Revenue from sales of x copies = 5x.

So, to at least recover his cost:

5000 + x = 5x

So, publisher must sell, x = 1250 copies.

The *point* **.** is a mathematical abstraction. It has negligible size and a great sense of position. Consequently, it is front and center in abstract existential reasoning.

The Universe is composed of *matter* and *radiant energy*. *Matter* is any kind of *mass-energy* that moves with velocities less than the velocity of light. *Radiant energy* is any kind of *mass-energy* that moves with the velocity of light.
