The landlord's favorite place to buy shrimp in new orleans was the cajun seafood market on claiborne and he did not hesitate to stock up on shrimp when he dropped by the shotgun double house he bought as an investment a few years ago. sadly, it was 685 miles one way to visit the property and even though gas was available at $1.88 per gallon and the car achieved 25 miles per gallon, it was an expensive trip. he packed a cooler with $12 worth of ice regardless of the quantity of shrimp he bought to bring home. the shrimp were a bargain at $7.99 per pound for jumbos and he always tried to fit 35 pounds of the crustaceans in the cooler. what is the landed cost of a pound of shrimp?
