For how many integer values of n will the value of the expression 4n + 7 be an integer greater than 1 and less than 120?
Choose the correct answer
A) 22	B) 24	C) 26	D) 28	E) 30
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; 120   4n&lt; 113   n &lt; 28. 25   n = (-infinity, .......-3, -2, -1, 0, 1, 2, .........upto 48)   Combining the two   -1.5 &lt; n&lt;48.25   n = 1 to 28 (48 integers)   and n = -1 and 0   so 30 integers.   30 is the answer
