Well I don't get what the other parts of the question is asking, but they can make 240 packs of pencils.
The answer is b I got it right on my test
10 pennies, 16 dimes, 19 nickles.
Sorry I'm not from US so I don't know your currency. Sorry about that. Hope what I have given you is enough. :)
Since there are a total of 4,200 residents and the question is asking for the amount in the south region, take the distribution number from the chart, 0.16, and multiply it by 4,200.
4200 ×.16 = 672
672 residents
