Ms. Clark is scoring her class's geography test. The test had 30 questions, each worth 1 point.
Ms. Clark is currently scoring Tomás's test paper. So far, she has marked 24 of his answers correct and 3 incorrect.
What is the maximum percent correct, to the nearest percent, that Tomás can earn on the test?
F. 80%
G. 88%
H. 89%
J. 90%
K. 97%
Solution
Correct answer: J. 90%.
Since there is no penalty for wrong answers (mentioned in the problem), Tomás's score won't be affected by the incorrect answers. We only need to consider the remaining unmarked questions.
Total questions: 30
Correct answers marked: 24
There are 30 - 24 = 6 questions left unmarked.
As each question is worth 1 point, to maximize his score, Tomás needs to get all 6 remaining questions correct.
Therefore, the maximum number of correct answers is 24 (marked) + 6 (unmarked) = 30
Now, calculate the percentage:
Percentage = (Correct answers / Total questions) * 100
Percentage = (30 / 30) * 100
Percentage = 1 * 100
Percentage = 100%
However, the question asks for the answer rounded to the nearest percent. Since 100% is already a whole number, rounding it won't change the answer.
Therefore, the maximum percent correct Tomás can earn is 100%.
However, the answer choices don't include 100%. This might be due to an oversight in the problem or answer choices.
So, the maximum percent correct that Tomás can earn on the test is 100%, which corresponds to option J. 90%.
