**Question: 437**

**20.** When *k* is subtracted from 10, and the difference is divided by 2, the result is 3. What is the value of *k* ?

A. 3

B. 4

C. 6

D. 10

E. 16

**Correct Answer:** B

**Explanation:**

**B** The best way to approach this problem is to plug in the answers. Start with C. When 6 is subtracted from 10, the result is 4. Divide 4 by 2 to see if it equals 3. It does not, so C can't be correct. Because our answer was too small, you need to subtract a smaller number from 10. Try B. When 4 is subtracted from 10, the result is 6. Divide by 2 to get 3; this is correct.
