450 miles divided by 15 miles per gallon = 30 gallons used on the one way trip.
At a cost of $3 per gallon that works out to 3 x 30 = $90 for a one way trip.
Assuming you also want to come home again, the return trip will cost 2x90 = $180 in total.
It will take you 2 x 30 gallons divided by 15 gallons in a tank = 4 full tanks for the return journey.
