Question

Jason decided that he will sell his stocks if their value per share (x) goes below $5 or above $15. Which compound inequality represents the values at which Jason will sell his stocks?

A. x > $5 or x < $15


B. x < $5 or x > $15


C. x > $5 and x < $15


D. x < $5 and x > $15

Answer 1

B. x < $5 or x > $15

Explanation:

The "or" in the problem statement gives you a clue that answer choices C and D can be rejected.

If x is the stock value, then value per share "below $5" means x < $5. This corresponds with answer choice B. Of course, "above $15" means x > $15, also corresponding to answer choice B.
