A printing company has eight presses, each of which can print 3600 copies per hour. It costs $5.00 to set up each press for a run and 10+6n dollars to run n presses for 1 h. How many presses should be used to print 50,000 copies of a poster most profitably. 2. Profit is revenue minus cost. In this case, revenue is presumed to be a fixed value because the number of copies is fixed at 50,000. Therefore, maximizing profit in this problem is the same as minimizing cost. Can you come up with a solution that minimizes the total cost? 3. Originally Posted by drumist Can you come up with a solution that minimizes the total cost?

Let $x$ be the number of presses used.
$5x+(10+6x)(50000/x)/3600$
