The Road Trip Gas & Carpool Expense Splitter computes exact vehicle gasoline consumption, aggregate fuel costs, and fair per-person shares for shared travel.

### Carpool Math & Fuel Consumption Equations The calculation distributes aggregate pump costs across all participating vehicle passengers: - **Total Gallons Required**: $$\text{Gallons Burned} = \frac{\text{Total Trip Miles}}{\text{Vehicle MPG}}$$ - **Aggregate Fuel Expenditure**: $$\text{Total Gas Bill} = \text{Gallons Burned} \times \text{Price per Gallon}$$ - **Individual Passenger Share**: $$\text{Share per Person} = \frac{\text{Total Gas Bill}}{\text{Number of Passengers}}$$

### Worked Travel Split Example Carpooling on a 350-mile road trip in a vehicle achieving 26 MPG with gasoline at $3.50 per gallon, divided evenly among 3 passengers: - **Fuel Consumption**: $350\text{ miles} / 26\text{ MPG} \approx 13.46\text{ gallons}$ - **Gross Pump Cost**: $13.4615 \times \$3.50 \approx \$47.12$ - **Per-Passenger Contribution**: $\$47.12 / 3 \approx \$15.71\text{ each}$
