When K is divided by N, the quotient is P and the remainder is P/2. What is the value of K in terms of N and P?
A. P(1 + N/2)
B. P(N + 1/2)
C. P/2(N + 1)
D. N/2(P + 1)
E. P(N + P/2)

There's a nice rule that says, "
If N divided by D equals Q with remainder R, then N = DQ + R"
For example, since 17 divided by 5 equals 3 with remainder 2, then we can write 17 = (5)(3) + 2
Likewise, since 53 divided by 10 equals 5 with remainder 3, then we can write 53 = (10)(5) + 3

So, for this question, we can write: K = NP + P/2
Factor out the P to get: K = P(N + 1/2)
