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

2 answers

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
