April scored 95% on her final exam. If each question was worth 3 points and there were 300 possible points on the exam, how many questions did April answer correctly?
| 95 | |

April scored 95% on the test meaning she earned 95% of the possible points on the test. There were 300 possible points on the test so she earned 300 x 0.95 = 285 points. Each question is worth 3 points so she got \( \frac{285}{3} \) = 95 questions right.
