A bread recipe calls for 2\(\frac{1}{2}\) cups of flour. If you only have \(\frac{1}{8}\) cup, how much more flour is needed?
| 2\(\frac{3}{8}\) cups | |
| 1\(\frac{7}{8}\) cups | |
| 1 cups | |
| 1\(\frac{1}{8}\) cups |
The amount of flour you need is (2\(\frac{1}{2}\) - \(\frac{1}{8}\)) cups. Rewrite the quantities so they share a common denominator and subtract:
(\( \frac{20}{8} \) - \( \frac{1}{8} \)) cups
\( \frac{19}{8} \) cups
2\(\frac{3}{8}\) cups

How many hours does it take a car to travel 75 miles at an average speed of 15 miles per hour?
| 2 hours | |
| 5 hours | |
| 4 hours | |
| 1 hour |
Average speed in miles per hour is the number of miles traveled divided by the number of hours:
speed = \( \frac{\text{distance}}{\text{time}} \)Solving for time:
time = \( \frac{\text{distance}}{\text{speed}} \)
time = \( \frac{75mi}{15mph} \)

Bob loaned Betty $500 at an annual interest rate of 6%. If no payments are made, what is the total amount owed at the end of the first year?
| $525 | |
| $540 | |
| $530 | |
| $520 |
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 $500
i = 0.06 x $500
No payments were made so the total amount due is the original amount + the accumulated interest:
total = $500 + $30Jennifer scored 84% on her final exam. If each question was worth 4 points and there were 400 possible points on the exam, how many questions did Jennifer answer correctly?
| 69 | |
| 71 | |
| 91 | |
| 84 |
Jennifer scored 84% on the test meaning she earned 84% of the possible points on the test. There were 400 possible points on the test so she earned 400 x 0.84 = 336 points. Each question is worth 4 points so she got \( \frac{336}{4} \) = 84 questions right.
