20

Step-by-step explanation:

Given that Tristan records the number of customers who visit the store each hour on a Saturday.

His data representing the first seven hours are 15, 23, 12, 28, 20, 18, and 23.

There are 7 entries and if written in ascending order 12,15,18,20,23,23,28

Median = middle entry -20

If one more entry is added then we have two middle entries and median would be the average of the two.

Hence if median is to remain the same, eighth hour no of customers visited should be 20

Answer is 20
