Answer:
$6.19
Explanation:
You want the difference in price per pound between the cost of salmon at store B and the cost at store A.
Cost per pound
The cost per pound is found by dividing the cost by the corresponding number of pounds. The difference in cost will be the difference of those quotients.
cost at Store B - cost at Store A = ($21.36/(2 lb)) -($8.98/(2 lb))
= ($21.36 -8.98)/(2 lb) = $6.19/lb
It is $6.19 per pound more expensive to buy salmon at Store B than at Store A.
