With this many pianos,how many piano tuners are there?We could begin the process of thinking about how often the pianos are tuned,how many pianos are tuned in one day,or how many days a piano tuner works,but that's not the point of rapid estimation.We instead think in orders of magnitude,and say that a piano tuner tunes roughly 10 to the second pianos in a given year,which is approximately a few hundred pianos.Given our previous estimate of 10 to the fourth pianos in Chicago,and the estimate that each piano tuner can tune 10 to the second pianos each year,we can say that there are approximately 10 to the second piano tuners in Chicago.
