If a mayor is elected with 83% of the votes cast and 49% of a town's 38,000 voters cast a vote, how many votes did the mayor receive?
| 15,455 | |
| 12,103 | |
| 16,013 | |
| 9,496 |
If 49% of the town's 38,000 voters cast ballots the number of votes cast is:
(\( \frac{49}{100} \)) x 38,000 = \( \frac{1,862,000}{100} \) = 18,620
The mayor got 83% of the votes cast which is:
(\( \frac{83}{100} \)) x 18,620 = \( \frac{1,545,460}{100} \) = 15,455 votes.

| 9 |
To fill a 15 gallon tank exactly halfway you'll need 7\(\frac{1}{2}\) gallons of fuel. Each fuel can holds 1\(\frac{1}{2}\) gallons so:
cans = \( \frac{7\frac{1}{2} \text{ gallons}}{1\frac{1}{2} \text{ gallons}} \) = 5
