Bob loaned April $1,500 at an annual interest rate of 4%. If no payments are made, what is the total amount owed at the end of the first year?
| $1,545 | |
| $1,530 | |
| $1,560 | |
| $1,575 |
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 $1,500
i = 0.04 x $1,500
No payments were made so the total amount due is the original amount + the accumulated interest:
total = $1,500 + $60If a mayor is elected with 73% of the votes cast and 80% of a town's 30,000 voters cast a vote, how many votes did the mayor receive?
| 17,280 | |
| 12,240 | |
| 17,520 | |
| 13,680 |
If 80% of the town's 30,000 voters cast ballots the number of votes cast is:
(\( \frac{80}{100} \)) x 30,000 = \( \frac{2,400,000}{100} \) = 24,000
The mayor got 73% of the votes cast which is:
(\( \frac{73}{100} \)) x 24,000 = \( \frac{1,752,000}{100} \) = 17,520 votes.

Diane scored 80% on her final exam. If each question was worth 2 points and there were 100 possible points on the exam, how many questions did Diane answer correctly?
| 31 | |
| 34 | |
| 46 | |

Diane scored 80% on the test meaning she earned 80% of the possible points on the test. There were 100 possible points on the test so she earned 100 x 0.8 = 80 points. Each question is worth 2 points so she got \( \frac{80}{2} \) = 40 questions right.
