For Community A:
Number of households: 10, 20, 40, 75
Total number of children: 26, 52, 104, 195
Average number of children per household in Community A:
Average = Total number of children / Number of households
Average = (26 + 52 + 104 + 195) / (10 + 20 + 40 + 75)
Average = 377 / 145
Average ≈ 2.60 children per household
For Community B:
Number of households: 12, 24, 50, 85
Total number of children: 30, 60, 125, 212.5
Average number of children per household in Community B:
Average = Total number of children / Number of households
Average = (30 + 60 + 125 + 212.5) /(12 + 24 + 50 + 85)
Average = 427.5 / 171
Average ≈ 2.50 children per household
Comparing the averages, we can conclude that Community A has a higher average number of children per household. This means that if there are 1,000 households, Community A would have more children than Community B.
To calculate the number of children in Community A if there are 1,000 households:
Number of children = Average number of children per household × Number of households
Number of children = 2.60 × 1,000
Number of children = 2,600
Therefore, the correct option is: Community A has the most children. There are 2,600 children in this community if there are 1,000 households.
