Problema Solution

Printing a newsletter costs $7.50 per copy plus $450 in printer fees. The copies are sold for $3 each. How many copies of the newsletter must be sold to break even?

Answer provided by our tutors

Let 'x' represent the number of copies sold, x is positive integer. 

The cost for producing x copies is: 7.50x + 450

The revenue from selling x copies is: 3x

To break even 7.50x + 450 must equals 3x that is:

7.50x + 450 = 3x

3.50x + 450 = 0

The above equality is not possible for x positive integer (3.50 + 450 is always greater than 0 for any x>0), meaning no matter how many copies are sold the company will never break even.
