Answer:
( a ) What is the smallest number of people that could have attended ?
34, 650
( b ) What is the greatest number of people that could have attended?
34, 749.
Explanation:
The estimate of the crowd to the nearest hundred is 34,700
Since we are rounding to the nearest hundred, the tens place determines whether the number is rounded up or down. So 34, 650 will round up to 34,700 but 34, 649 will round down to 34, 600
The smallest number that will be rounded to 34, 700 is 34, 650
(if it was one lower, 34, 649, that would be rounded down to 34, 600)
The largest number that can be rounded down to 34, 700 is 34, 749.
(If it was 1 more larger, i.e. 34, 750 it would be rounded up to 34, 800 )
In short, if rounding to the nearest 100, the smallest number will be the number - 50. Here it is 34, 700 - 50 = 34, 650
The largest number is found by adding 49 to the number so it will be
34, 749
