I did say the answer is $35. Because, you should use the highest factor or whatever operation the problem is using, to find the answer. Not sure if it's some two-step problem....
Answer:
If you go to fill up your car, the amount of gasoline in your tank influences how much you pay. The amount is a volume calculation, regardless of whether you fill up with gallons or liters of gasoline or other fuels. On a lesser scale, when filling a gas can to transfer to another vehicle or utilize the gas to power another device, volume is used to calculate the amount needed.
Hope this helps!
