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)?
Answer provided by our tutors
if competitor runs 100
then brand x runs 123 which is 23% more
so we get proportion
100/123 = x / 62300
x = 100*62300/123
x =50650.41 rounded to 50650
