Answer:
Store #1
Explanation:
Store #1 sells many more articles at $30 than store #2, which should help the sales of that new $30 hammer. Store #1 sold 80+ units of that price, while store #2 didn't sell 20, so store #1 outsells store #2 by a factor of 4+ for articles of $30.
Generally store #1 sells more of the cheaper items (less than $90) while store #2 sells more of the most expensive items ($90+).
