If a mayor is elected with 87% of the votes cast and 90% of a town's 29,000 voters cast a vote, how many votes did the mayor receive?
| 22,707 | |
| 20,880 | |
| 19,575 | |
| 23,229 |
If 90% of the town's 29,000 voters cast ballots the number of votes cast is:
(\( \frac{90}{100} \)) x 29,000 = \( \frac{2,610,000}{100} \) = 26,100
The mayor got 87% of the votes cast which is:
(\( \frac{87}{100} \)) x 26,100 = \( \frac{2,270,700}{100} \) = 22,707 votes.
A triathlon course includes a 100m swim, a 50.8km bike ride, and a 13.8km run. What is the total length of the race course?
| 35.6km | |
| 64.7km | |
| 57.2km | |
| 27.6km |
To add these distances, they must share the same unit so first you need to first convert the swim distance from meters (m) to kilometers (km) before adding it to the bike and run distances which are already in km. To convert 100 meters to kilometers, divide the distance by 1000 to get 0.1km then add the remaining distances:
total distance = swim + bike + run
total distance = 0.1km + 50.8km + 13.8km
total distance = 64.7km
What is the next number in this sequence: 1, 9, 17, 25, 33, __________ ?
| 41 | |
| 33 | |
| 43 | |
| 32 |
The equation for this sequence is:
an = an-1 + 8
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 + 8
a6 = 33 + 8
a6 = 41

Ezra loaned Charlie $100 at an annual interest rate of 9%. If no payments are made, what is the interest owed on this loan at the end of the first year?
| $18 | |
| $12 | |
| $42 | |
| $9 |
The yearly interest charged on this loan is the annual interest rate multiplied by the amount borrowed:
interest = annual interest rate x loan amount
i = (\( \frac{6}{100} \)) x $100
i = 0.09 x $100
i = $9
