A tiger in a zoo has consumed 70 pounds of food in 7 days. If the tiger continues to eat at the same rate, in how many more days will its total food consumtion be 100 pounds?
| 7 | |
| 3 | |
| 10 | |
| 2 |
If the tiger has consumed 70 pounds of food in 7 days that's \( \frac{70}{7} \) = 10 pounds of food per day. The tiger needs to consume 100 - 70 = 30 more pounds of food to reach 100 pounds total. At 10 pounds of food per day that's \( \frac{30}{10} \) = 3 more days.

If a mayor is elected with 54% of the votes cast and 79% of a town's 39,000 voters cast a vote, how many votes did the mayor receive?
| 27,729 | |
| 24,956 | |
| 17,562 | |
| 16,637 |
If 79% of the town's 39,000 voters cast ballots the number of votes cast is:
(\( \frac{79}{100} \)) x 39,000 = \( \frac{3,081,000}{100} \) = 30,810
The mayor got 54% of the votes cast which is:
(\( \frac{54}{100} \)) x 30,810 = \( \frac{1,663,740}{100} \) = 16,637 votes.

5 x 4 x 3 x 2 x 1 |
|

|
4 x 3 x 2 x 1 |
A factorial has the form n! and is the product of the integer (n) and all the positive integers below it. For example, 5! = 5 x 4 x 3 x 2 x 1 = 120.
