+103 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?
+237 (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.
