Answer: 19 people
Explanation:
If every 4th customer received a free gingerbread man cookie and 29 cookies were given away then the number of customers that came were:
= 4 * 29
= 116 customers
Because 116 customers came, they were able to give 29 cookies by giving one to every 4th customer.
If there were 116 customers, the number of customers who got the free candy canes would be:
= 116/6
= 19.3
= 19 people
