Answer:
Explanation:
The sentence that represents the number of points in the problem is OD. The number of multiple-choice question points plus the number of short-answer question points is 60.
The problem states that the test is worth 60 points, and that multiple-choice questions are worth 2 points each and short-answer questions are worth 5 points each. If the test has 15 questions, then there must be some number of multiple-choice questions and some number of short-answer questions. The total number of points for the multiple-choice questions and the short-answer questions must add up to 60, so the answer is OD.
The other answer choices are incorrect. OA is incorrect because it says that the number of multiple-choice question points times the number of short-answer question points is 60. This is not possible, because the number of points for a question cannot be multiplied by the number of points for another question. OB is incorrect because it says that the number of multiple-choice question points plus the number of short-answer question points is 15. This is not possible, because the total number of points for the test is 60, not 15. OC is incorrect because it says that the number of multiple-choice question points minus the number of short-answer question points is 15. This is not possible, because the number of points for a question cannot be subtracted from the number of points for another question.
