Calculate Population Total: Calculate the total population of New York City. To find the total population, multiply the population density by the area of the city. Population density = 27,000 residents per square mile Area of New York City = 301 square miles Total population = Population density × Area Total population = 27,000 residents/mile² × 301 miles²Find Total Population: Perform the multiplication to find the total population. Total population = 27,000 × 301 Total population = 8,127,000 residentsCalculate Subway Cars: Calculate the number of subway cars based on the population. We know there is approximately 1 subway car for every 1,300 residents. Number of subway cars = Total population ÷ Number of residents per subway car Number of subway cars = 8,127,000 ÷ 1,300Determine Number of Subway Cars: Perform the division to find the number of subway cars. Number of subway cars = 8,127,000 ÷ 1,300 Number of subway cars ≈ 6,251.54Round to Nearest Hundred: Round the number of subway cars to the nearest one hundred. To round to the nearest one hundred, we look at the tens digit. If it is 5 or more, we round up. If it is less than 5, we round down. In this case, the tens digit is 5, so we round up. Rounded number of subway cars = 6,300
