If a mayor is elected with 85% of the votes cast and 69% of a town's 43,000 voters cast a vote, how many votes did the mayor receive?

50% Answer Correctly
23,439
18,989
21,066
25,220
Solution

If 69% of the town's 43,000 voters cast ballots the number of votes cast is:

(\( \frac{69}{100} \)) x 43,000 = \( \frac{2,967,000}{100} \) = 29,670

The mayor got 85% of the votes cast which is:

(\( \frac{85}{100} \)) x 29,670 = \( \frac{2,521,950}{100} \) = 25,220 votes.
