# 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?

 A) 48 B) 49 C) 50 D) 51

Explanation:

1 < 4n + 7 < 200

n can be 0, or -1

n cannot be -2 or any other negative integer or the expression 4n + 7 will be less than1.

The largest value for n will be an integer < (200 - 7) /4

193/4 = 48.25, hence 48

The number of integers between -1 and 48 inclusive is 50
