Answer:
A. 15$
Explanation:
The median is the middle value. Looking at the ranges of both, here's what we know:
Store X:
Range: 30-105
Store Y:
Range: 20-85
Now for the medians!
Usually, we would cross out values on each side until we find the middle. but this is so large, we can cross out in goups of 5 until we find it.
Store Y's median is 55
Store X's median is 70
These median prices are 15 dollars apart! That gives you your answer. Have a great day!
