My homework question states: " My car is about out of gas, and I'm trying to decide which gas station to go to. Some gas is cheaper, but the distance to drive to it is farther. I've researched 5 gas stations. The gas prices per gallon are listed in price. The distance in miles to each station, respectively, is in dist. I want you to make me a table that lists triples of (price, distance, the total cost of buying 13 gallons of fuel). The total cost includes the cost of filling my tank plus the cost of gas required to get me to the station."

I am given price and dist, listed below..Feel free to open the attachment in mathematica and run my code to actually see what I'm trying to do. I posted the code in here also..

price = {3.95, 3.93, 3.89, 3.79 , 3.87};
dist = {1.0, .8, 3.3, 9.6, 7.9};

This is my function I created, I know this is right.

total[price_, dist_] := (price*13) + (price*dist/40); 

I know my function must include a price * 13 because we are interested in the total cost of 13 gallons plus the cost of gas required to get to the station. I must know how much mileage per gallon our car gets so I chose 40 because I'm driving an eco friendly vehicle. ;)

Next is my bit of code to actually run and produce this table I need..

clear[Num5];
Num5 = Table[{dist, price, total[price, dist]}, {price, dist}];
Num5 // TableForm

I know there is something wrong with my above code, I want to produce a table that shows price, dist and total price, but I seem to be getting something else..I've tried altering my code multiple times. I'm pretty stumped. If anyone can lead me ina different direction that would be awesome. I feel like for the most part I am on the right track.
