A cereal company puts a 10 cents-off coupon in every other box of cereal it packages. It puts a pencil in every fifth box. It puts a coupon for a free hamburger in every eighth box. Out of the first 100 boxes, how many will have a 10 cents-off coupon, a pencil, and a coupon for a free hamburger?

(1) a 10 cents off coupon, every other box, 2

(2) a pencil, 5

(3) a coupon for a free hamburger, 8

If there are three, that means it's the least common multiple of 2,5, and 8

becuase it's : 40,

So 100 / 40 = 2 ... 20.

So have 2 boxes.
