Answer:
953 Citizens
Explanation:
So here basically you add up all the citizens first that were in the survey.
25+38+11+6 = 80 total participants
38 of which are Rock Fans
38/80 = 0.475%
0.475% of the total citizens = Estimate of Rock fans in entire Throne County
0.475 * 2006 = 952.85 Citizens
You can't have .85 of a citizen so you round up to 953 Citizens.
Or you can round down if it was less than 952.5.
So the Answer is 953 Citizens
