For how many integer values of n will the value of the expression 4n + 7 be an integer greater than 1 and less than 100?	Choose the correct answer.
A) 30 B) 28 C) 27 D) 25 E) 26
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; 100   4n&lt; 93   n &lt; 23. 25   n = (-infinity, .......-3, -2, -1, 0, 1, 2, .........upto 23)   Combining the two   -1.5 &lt; n&lt;23.25   n = 1 to 23 (23 integers)   and n = -1 and 0   so 25 integers.   25 is the answer
