If a mayor is elected with 85% of the votes cast and 39% of a town's 26,000 voters cast a vote, how many votes did the mayor receive?
| 5,273 | |
| 8,619 | |
| 8,416 | |
| 5,476 |
If 39% of the town's 26,000 voters cast ballots the number of votes cast is:
(\( \frac{39}{100} \)) x 26,000 = \( \frac{1,014,000}{100} \) = 10,140
The mayor got 85% of the votes cast which is:
(\( \frac{85}{100} \)) x 10,140 = \( \frac{861,900}{100} \) = 8,619 votes.
The total water usage for a city is 10,000 gallons each day. Of that total, 27% is for personal use and 52% is for industrial use. How many more gallons of water each day is consumed for industrial use over personal use?
| 2,500 | |
| 1,400 | |
| 17,500 | |
| 7,700 |
52% of the water consumption is industrial use and 27% is personal use so (52% - 27%) = 25% more water is used for industrial purposes. 10,000 gallons are consumed daily so industry consumes \( \frac{25}{100} \) x 10,000 gallons = 2,500 gallons.

Find the average of the following numbers: 7, 5, 10, 2.
| 2 | |
| 6 | |
| 9 | |
| 10 |
To find the average of these 4 numbers add them together then divide by 4:
\( \frac{7 + 5 + 10 + 2}{4} \) = \( \frac{24}{4} \) = 6
