Answer:
C. The median purchase at Corner Mart for the month of July was $15
Explanation:
Option 1 and 2 don't make sense
Option 1 doesn't make sense because it says "Custumers who spend more than $20 go to the Local Grocery instead of the Corner Mart."
Option 2 doesn't make sense, because they both have the same amount of customers, which is 9 customers
Option 3 is correct
Because the median represents the middle value of a data set when it is placed in order from smallest to largest
And the middle value of the corner Mart is $15
Option 4 is wrong, because one spent more than $25
