Question

Mr. Radon's favorite place to buy shrimp in New Orleans was the Cajun Seafood market on Claiborne. He always stocked up on shrimp whenever he inspected the house he bought as an investment a few years ago. The trip 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 and lengthy trip. The cheapest plane tickets that were routinely available cost $199 round trip, but occasionally there was a super sale where the price dropped lower than that. He always packed a cooler with $12 worth of ice regardless of how much shrimp he actually bought. 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 price of round trip airfare that would make the landed cost of a pound of shrimp the same for both driving and flying?

$113

$147

$103

$169

Answer 1

$103

In order to travel 25 miles the number of gallons of fuel required is 1

Therefore in order to travel 685 miles the number of gallons of fuel required is (1/25)*685

= 27.4

The cost of 27.4 gallon fuel is = 27.4*1.88

= $51.51

For both ways the cost would be 51.51*2

= $103

Hence this would be the price of round trip airfare in order to make it equal.
