Yes.

120 * 0.7 = _______ questions to get a C

To find out how many questions Mwajuma should answer correctly, we need to calculate 70% of the total marks.

Step 1: Calculate the total marks
The total marks for the exam can be determined by multiplying the number of questions by the marks allocated per question. In this case, there are 120 questions and each question carries one mark. So, the total marks would be 120.

Step 2: Calculate 70% of the total marks
To find out how many marks Mwajuma needs to receive a grade C, we need to calculate 70% of the total marks.
70% of 120 is (70/100) * 120 = 84 marks.

Step 3: Determine the number of questions she should answer correctly
Since each question carries one mark, we can conclude that Mwajuma needs to answer 84 questions correctly to score 84 marks.

Therefore, Mwajuma should answer 84 questions correctly to receive a grade C in the subject.
