A) 30,000,000
B) 40,000,000
C) 35,000,000
D) 50,000,000

Answer 1

To estimate the population of a city to the nearest ten million, we round the given population.

Step-by-step explanation:

To estimate the population to the nearest ten million, we need to round the given population, 38,802,500, to the nearest ten million. To do this, we look at the digit in the ten million place, which is the second digit from the left. If this digit is 5 or greater, we round up to the next ten million. If it is less than 5, we round down to the current ten million. In this case, the digit in the ten million place is 8, which is greater than 5, so we round up. Therefore, the estimated population to the nearest ten million is 40,000,000.
