Calculate the number of voters who DID vote by finding (100тИТX)% of total, and sum the results. For example, in town A, calculate 85% of 30000 which is 30000├Ч0.85=25500.
Students often calculate the percentage of people who DO NOT vote instead of those who DO vote.
Calculate voters for Town A
Town A total is 30000 and 15% did not vote, so 85% voted.
30000├Ч0.85=25500
Calculate voters for Town B
Town B total is 13500 and 20% did not vote, so 80% voted.
13500├Ч0.80=10800
Calculate voters for Town C
Town C total is 28000 and 18% did not vote, so 82% voted.
28000├Ч0.82=22960
Find the total
Sum the number of voters from all three towns.
25500+10800+22960=59260
B is correct because the sum of people who voted in towns A, B, and C is 25500+10800+22960=59260.
Always verify if the question asks for the total of a subset or the entire data set to avoid unnecessary calculations.
