Explanation:

Given : The movie house gives away a 5$ coupon for every 4 movies purchased they give away a bag of popcorn for every 3 movies purchased.

To find : How many movies would you have to purchase in all before receiving both ?

Solution :

To get the result we have to find the LCM of 4 and 3,

For every 4 movies purchased,

The multiples of 4 are 4, 8, 12

For every 3 movies purchased,

The multiples of 3 are 3, 6, 9, 12

LCM (3,4) = 12

Therefore, 12 movies would you have to purchase in all before receiving both.
