ASVAB Question on Signed Numbers

In my ASVAB prep course, I focus on signed numbers.  As an ASVAB tutor, I remind the students in my class that being able to master signed numbers plays an important role in helping to improve one’s ASVAB math score.  Adding and subtracting positive and negative numbers is a critical skill in ASVAB math.  It is important in algebra, order of operations, and word problems.  A number of students struggle with this concept.  Do you know how to answer this problem? The answer will be posted tomorrow.
