Final answer:
To determine how much more expensive it is to buy salmon at Store B than at Store A, you can compare the prices per pound at both stores.
Step-by-step explanation:
To find how much more expensive it is to buy salmon at Store B than at Store A, we need to compare the prices per pound at both stores.
The equation for the total cost of buying salmon at SuperGrocery A is y = 9.07x, where y represents the total cost and x represents the pounds of salmon bought.
We don't have the equation for the graph of SuperGrocery B, so we can't directly compare the prices.
However, based on the information given, we can use the slope of the line on the graph to determine the difference in price per pound between the two stores.
