The total water usage for a city is 35,000 gallons each day. Of that total, 25% is for personal use and 60% is for industrial use. How many more gallons of water each day is consumed for industrial use over personal use?
| 12,250 | |
| 9,450 | |
| 10,800 | |
| 5,000 |
60% of the water consumption is industrial use and 25% is personal use so (60% - 25%) = 35% more water is used for industrial purposes. 35,000 gallons are consumed daily so industry consumes \( \frac{35}{100} \) x 35,000 gallons = 12,250 gallons.

The greatest common factor (GCF) is the greatest factor that divides two integers.
A menswear store is having a sale: "Buy one shirt at full price and get another shirt for 35% off." If Monty buys two shirts, each with a regular price of $19, how much money will he save?
| $6.65 | |
| $7.60 | |
| $0.95 | |
| $9.50 |
By buying two shirts, Monty will save $19 x \( \frac{35}{100} \) = \( \frac{$19 x 35}{100} \) = \( \frac{$665}{100} \) = $6.65 on the second shirt.
Which of these numbers is a factor of 24?
| 16 | |
| 15 | |
| 18 | |
| 8 |

If there were a total of 400 raffle tickets sold and you bought 16 tickets, what's the probability that you'll win the raffle?
| 5% | |
| 4% | |
| 11% | |
| 8% |
You have 16 out of the total of 400 raffle tickets sold so you have a (\( \frac{16}{400} \)) x 100 = \( \frac{16 \times 100}{400} \) = \( \frac{1600}{400} \) = 4% chance to win the raffle.
