The table below represents what Olivia would pay in dollars and cents, yy, for xx bottles of pineapple juice at store B.

How much less is a bottle of pineapple juice at Store B than at Store A?
To find the difference in price between store A and store B, we need to compare the cost of a single bottle of pineapple juice at each store.
From the information given, we can see that at store A, the price of x bottles of pineapple juice can be represented by the equation y = x * (cost per bottle).
From the graph, we can determine that the cost per bottle at store A is $0.57.
Comparing this to the table for store B, we can see that the cost per bottle at store B is as follows:
For 4 bottles, the total cost is $2.28. So, the cost per bottle is $2.28/4 = $0.57.
For 16 bottles, the total cost is $9.12. So, the cost per bottle is $9.12/16 = $0.57.
For 18 bottles, the total cost is $10.26. So, the cost per bottle is $10.26/18 = $0.57.
For 20 bottles, the total cost is $11.40. So, the cost per bottle is $11.40/20 = $0.57.
Therefore, the cost per bottle at store B is also $0.57.
Since the cost per bottle at both stores is the same, the bottles of pineapple juice at store B are not less expensive than at store A.
