Answer to Question 1

b
RATIONALE: The slack value for each less-than-or-equal-to constraint indicates the difference between the left-hand and right-hand values for a constraint.

Answer to Question 2

Your score is 20.

RATIONALE: If your score is at the 75th percentile, then you have a higher score than 75 of the test takers. Your score can be calculated using the Excel function NORM.INV(0.75,18,3) = 20.
