There are 2 companies working in city A: Newton and Garfield
Newton exports all their products outside the city and Garfield only sells their products within the city. Newton experiences growth, so it hires 100 more workers, all of whom come to reside in city A. Because of this, Garfield - at the first stage - hires 60 more workers.
From these facts, and working under the assumption that every additional stage of growth will cause a rise of 60 percent to the number of workers that were added in the previous stage, what is the total number of workers that will be added to city A?
