How many integers n are there such that 1< 4n +4 < 20? Choose the correct choice from the following answers:
A) Five
B) Four
C) Three
D) Two
E) One
Solution:   1&lt; 4n + 4 &lt; 20   1&lt; 4n + 4 &lt; 20   We first subtract 4 from all three parts of the inequality, and we obtain:   -3 &lt; 4n &lt; 16   Next, we divide both sides of the inequality by 4 and we get:   -3/4 &lt; n &lt; 4   The answer is Four
