Answer:
The answer is A. $539.
Explanation:
Based off examining the table, the vertical label represents the city from which the responses were gathered, and the horizontal label represents the team that those in the responses support.
When it's asking for the responses "by the Steelers fans", we can go to the horizontal labels, look for the one for the Steelers, and find where it intersects with the vertical label for Houston. The place they intersect represents the responses that are both by Steelers fans and from Houston.
The amount for yearly spending in that location is $539, so that's the answer.
Hope this helps!
