Suppose the population of a large city like New York City is about 3 × 106 people, with about 2.9 people per household. Approximately 1 household in 18.7 has a piano. The piano keyboard has about 64 notes (8 octaves) with about 2 strings per note. A piano should be tuned once per year (365.25 days). A piano tuner can tune about 4 pianos per day. And finally, piano tuners work 248 days per year. Determine how many piano tuners are there in New York City?
