Question

The ratio of calls answered by machine to those answered by a possible client is 20
to 1. Every day Bug-U-Often makes 10,500 phone solicitations. How many of
these calls are answered by a possible client?

Answer 1

You can set up a proportion: 1/20 = x/10500. Then you cross multiply to get 20x=10500. So, the number of calls that are answered would be 525.
