Inputs (The Math)
- Trip Distance450 miles
- Vehicle Efficiency25 MPG
- Gas Price$3.50 / gallon
Outputs (The Result)
- Fuel Required18 gallons
- Total Cost$63.00
Why it works this way
First, divide the distance by the efficiency to find how many gallons are needed (450 / 25 = 18). Then, multiply the gallons by the price per gallon to find the total trip cost.
- Gas prices remain exactly $3.50 for the entire trip.
