April scored 84% on her final exam. If each question was worth 2 points and there were 180 possible points on the exam, how many questions did April answer correctly?
| 84 | |
| 74 | |
| 86 | |
| 76 |
April scored 84% on the test meaning she earned 84% of the possible points on the test. There were 180 possible points on the test so she earned 180 x 0.84 = 152 points. Each question is worth 2 points so she got \( \frac{152}{2} \) = 76 questions right.
Damon loaned Damon $200 at an annual interest rate of 6%. If no payments are made, what is the interest owed on this loan at the end of the first year?
| $12 | |
| $99 | |
| $25 | |
| $6 |
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 $200
i = 0.06 x $200
i = $12
A circular logo is enlarged to fit the lid of a jar. The new diameter is 60% larger than the original. By what percentage has the area of the logo increased?
| 35% | |
| 22\(\frac{1}{2}\)% | |
| 25% | |
| 30% |
The area of a circle is given by the formula A = πr2 where r is the radius of the circle. The radius of a circle is its diameter divided by two so A = π(\( \frac{d}{2} \))2. If the diameter of the logo increases by 60% the radius (and, consequently, the total area) increases by \( \frac{60\text{%}}{2} \) = 30%

How many 2 gallon cans worth of fuel would you need to pour into an empty 12 gallon tank to fill it exactly halfway?
| 2 | |
| 3 | |
| 6 | |
| 3 |
To fill a 12 gallon tank exactly halfway you'll need 6 gallons of fuel. Each fuel can holds 2 gallons so:
cans = \( \frac{6 \text{ gallons}}{2 \text{ gallons}} \) = 3
