Question

A deli has a special one-day event to celebrate its anniversary. On the day of the event, every eighth customer receives a free drink. Every twenty-eighth customer receives a free sandwich. If 200 customers show up for the event, how many of the customers will receive both a free drink and a free sandwich?

Answer 1

Answer: The answer is just 3 people will get BOTH the free drink and free sandwich.

Explanation:

Every 8th = 1 free drink

Every 28th = 1 free sandwich

200 costumers showed

Add 28 to 28 until you reach the closest to 200 so: 28,56,84,112,140,168,196

Then add 8 to 8 until 200, every number that match the 28th sequence is 1 costumer that receives 1 drink and 1 sandwich

The match numbers are 56,112,168

Answer 2

the number of common customers are 8 in number
