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.
12 miles / 3 gallons = 4 miles per gallon So for 1 gallon, the car can travel 4 miles.
232.96 total. The capacity of the tank is irrelevant. To travel 416 miles at a rate of 5 miles per gallon uses 83.2 gallons. 83.2 gallons at a cost of 2.80 per gallon is 232.96 !
