Problema Solution

solve problem by stating the equation you used.

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
