Brand X copier advertises that its copiers run 23% longer between service calls than its competitor. If Brand X copiers run 62,300 copies between service calls, how many copies would the competitor run (to the nearest copy)?

Solution:

We assume the competitor run P copies.

(1+23%)*P = 62,300

P = 62,300/1.23 = 50,650

So the competitor run 50,650 copies
