The formula to calculate the trip gas price is:
\[ GP = \frac{D}{FE} \times C \]
where \( GP \) is the trip gas price (\$), \( D \) is the total trip distance (miles), \( FE \) is the fuel efficiency of the car (MPG), and \( C \) is the average cost of gas (\$/gallon).
The trip gas price is the total cost of gas required for a trip, calculated based on the distance of the trip, the fuel efficiency of the vehicle, and the average cost of gas. This is useful for budgeting and planning road trips.
Let's assume we have the following values:
Step 1: Divide the total trip distance by the fuel efficiency:
\[ \frac{D}{FE} = \frac{300}{25} = 12 \]
Step 2: Multiply by the average cost of gas:
\[ GP = 12 \times 3.50 = 42 \]
Therefore, the Trip Gas Price is \( GP = \$42 \).
