Answer:
A. 5a+10
Step-by-step explanation:
a + 20 + 4a - 10
= a + 4a + 20 - 10
= 5a + 10
First we need to find the median of the data given. To do that, it should be in order:
12, 15, 18, 20, 23, 23, 28
So the median is 20
The only way to guarantee that the median doesn't change would be for the eight hour to have 20 visitors so the new data would be:
12, 15, 18, 20, 20, 23, 23, 28
Hope this helps!
