For how many integer values of n will the value of the expression 4n + 7 be an integer greater than 1 and less than 200?	Choose the correct choice from the following.
A) 48  B) 49  C) 50  D) 51  E) 52
From first constraint   4n+7 &gt; 1   4n&gt; -6   n &gt; -(3/2)   n&gt; -1.5 (n = -1, 0, 1 ,2 3........ upto infinity)   From second constraint   4n+7 &lt; 200   4n&lt; 193   n &lt; 48. 25   n = (-infinity, .......-3, -2, -1, 0, 1, 2, .........upto 48)   Combining the two   -1.5 &lt; n&lt;48.25   n = 1 to 48 (48 integers)   and n = -1 and 0   so 50 integers.   50 is the answer
