At the grand opening of a movie theater, every 12th customer received a free bag of popcorn and every 30th customer received a free box of candy. Which customer will be the first to receive both items?

The 60th customer

Step-by-step explanation:

because the LCM of 12 and 30 is 60...

Hope This Helps :)... -_-

Your answer would be the 60th

Step-by-step explanation:

This is your solution due to the fact that when you find the multiples of 12 and 30 you will realize that that's the first number they meet at, let me show you.

Multiples of 12 - 12, 24, 36, 48, 60

Multiples of 30 - 30, 60, 90, 120, 150

So The Least Common Denominator is 60!

Thus that is how I know that the 60th customer at the movie theater would get both items for free.

Hope This Helped!

36

Step-by-step explanation:

One roll length is = 9 feet

1 foot = 12 inches

9 feet = 12 *9 = 108 inches

There are 5 rolls

Total length of 5 rolls = 108 * 5 = 540

540 divided by 15

540/15 = 36

The greatest number of 15-inch pieces the seamstress can cut from 5 of these rolls of ribbon is 36.
