A local bakery celebrated its one-year anniversary on Saturday. On that day, every 4th customer received a free cookie. Every 6th customer received a free muffin. Did the 30th customer receive a free cookie, a free muffin, both, or neither? Show or explain how you got your answer.

Free muffin. To receive a free cookie, your customer number must be a multiple of 4. To receive a free muffin, your customer number must be a multiple of 6. 

30 is not a multiple of 4. But, it is a multiple of 6. 6 x 5 = 30

The 30th customer is the 5th customer to receive a free muffin
