If p and q are positive integers, how many integers are larger than pq and smaller than p(q + 4)? Pick one.
A) 4p - 1	B) P + 2	C) p – 2	D) 2p – 1	E) 2p + 1
The number of integers between x and y, where x&gt;y is (x-y)-1. For example, the number of integers between 1 and 5 is  (5-1)-1=

3: 2, 3, and 4.   Thus, the number of integers between pq and p(q+4)=pq+4p is (pq+4p-pq)-1=4p-1.   4p - 1nswer: 4p - 1.
