If a mayor is elected with 55% of the votes cast and 69% of a town's 49,000 voters cast a vote, how many votes did the mayor receive?
| 17,581 | |
| 27,386 | |
| 18,595 | |
| 21,638 |
If 69% of the town's 49,000 voters cast ballots the number of votes cast is:
(\( \frac{69}{100} \)) x 49,000 = \( \frac{3,381,000}{100} \) = 33,810
The mayor got 55% of the votes cast which is:
(\( \frac{55}{100} \)) x 33,810 = \( \frac{1,859,550}{100} \) = 18,595 votes.
