A student has taken four tests and has an average score of 82. To achieve an average score of 85 across five tests, what score must the student get on the fifth test?

✓ Correct Answer: Option D

The total score for four tests is 4 * 82 = 328. To have an average of 85 over five tests, the total score needed is 5 * 85 = 425. Therefore, the score needed on the fifth test is 425 - 328 = 97.
