To discourage guessing, Mrs. Lopez made a test - grading scheme shown at the right. On a 100-item test, Jessa left 11 answers blank and answered and 48 question correctly. What is her score?

It is problem solving involving addition in integers

Out of 100 questions,

48 correct answers
11 blank
41 wrong answers
total 100

We don't get to see the scheme.
Assume the scheme says:
1 point for each correct answer,
-1 point for each incorrect answer,
0 for leaving it blank.
So total points
=48-41-0
=7

100-41= 59

To calculate Jessa's score on the test, we need to understand the grading scheme.

According to the given grading scheme, each incorrect answer deducts 1/4 point from the total score, and each correct answer is worth 2 points.

Jessa left 11 answers blank, which means she did not receive any points or deductions for those questions. Therefore, we only need to consider the 48 questions she answered correctly.

To calculate Jessa's score, we can follow these steps:

1. Calculate the points earned for the correct answers:
Jessa answered 48 questions correctly, and each correct answer is worth 2 points.
So, the points earned from the correct answers = 48 × 2 = 96 points.

2. Calculate the points deducted for the incorrect answers:
Jessa did not answer any incorrect questions, so there are no points deducted.

3. Calculate the total score:
Total score = Points earned for correct answers - Points deducted for incorrect answers
= 96 points - 0 points
= 96 points.

Therefore, Jessa's score is 96 points.
