How many integers between \(18\) and \(3399\) are multiples of \(17\)?
\(A. 198\)
\(B. 199\)
\(C. 200\)
\(D. 201\)
\(E. 202\)
One approach:
Let's list the multiples of 17 that are between 18 and 3399 :
34 =
2(17)
51 =
3(17)
68 =
4(17)
85 =
5(17)
.
.
.
3383 =
199(17)
So, the number of multiples of 17 is EQUAL to the number of integers from
2 to
199 inclusive
ASIDE: A nice rule says:
the number of integers from x to y inclusive equals y - x + 1So, the number of integers from
2 to
199 inclusive =
199 -
2 + 1 = 198
Answer: A
