If a mayor is elected with 80% of the votes cast and 59% of a town's 42,000 voters cast a vote, how many votes did the mayor receive?
| 13,381 | |
| 21,806 | |
| 13,629 | |
| 19,824 |
If 59% of the town's 42,000 voters cast ballots the number of votes cast is:
(\( \frac{59}{100} \)) x 42,000 = \( \frac{2,478,000}{100} \) = 24,780
The mayor got 80% of the votes cast which is:
(\( \frac{80}{100} \)) x 24,780 = \( \frac{1,982,400}{100} \) = 19,824 votes.
What is the next number in this sequence: 1, 3, 7, 13, 21, __________ ?
| 39 | |
| 33 | |
| 31 | |
| 29 |
The equation for this sequence is:
an = an-1 + 2(n - 1)
where n is the term's order in the sequence, an is the value of the term, and an-1 is the value of the term before an. This makes the next number:
a6 = a5 + 2(6 - 1)
a6 = 21 + 2(5)
a6 = 31

There are 3 4-passenger taxis available so that's 3 x 4 = 12 total seats. There are 15 people needing transportation leaving 15 - 12 = 3 who will have to find other transportation.
