Example Calculation

Imagine you’re planning a trip of 300 miles.

  • Your car’s fuel efficiency: 30 MPG
  • Gas price per gallon: $3.80

Step 1: Calculate fuel needed

Fuel Needed=DistanceMPG=30030=10 gallons\text{Fuel Needed} = \frac{Distance}{MPG} = \frac{300}{30} = 10 \, \text{gallons}Fuel Needed=MPGDistance​=30300​=10gallons

Step 2: Calculate total cost

Total Cost=Fuel Needed×Gas Price=10×3.80=$38.00\text{Total Cost} = \text{Fuel Needed} \times \text{Gas Price} = 10 \times 3.80 = \$38.00Total Cost=Fuel Needed×Gas Price=10×3.80=$38.00

➡️ Result: You’ll need 10 gallons of fuel costing $38.00 for the trip.
