Final Answer:
The remaining gallons of gas in Royston's car's tank after refueling during the trip can be calculated using the formula: Remaining gas = (Initial gallons + Refueled gallons) - Gas consumed. Therefore, the remaining gallons of gas in the tank are (Initial gallons + Refueled gallons) - Gas consumed.
Step-by-step explanation:
To find the amount of gas remaining in Royston's car after refueling during the trip, we can use a simple formula based on the gas consumed, initial gallons, and refueled gallons. Let the initial amount of gas in the car be represented by "I," the amount refueled at the station be represented by "R," and the gas consumed during the trip be represented by "C." The formula to calculate the remaining gas would be: Remaining gas = (I + R) - C.
During the trip, Royston started with an initial amount of gas in the tank (I) and refueled the car at a gas station, adding a specific amount (R) of gas. So, the total gas available became (I + R). As the trip progressed, the car consumed a certain amount of gas (C). The remaining gas in the tank can be calculated by subtracting the gas consumed from the total gas available, giving us the final amount of gas remaining after the refueling stop.
This formula is applicable regardless of the specific numerical values involved. By plugging in the actual quantities of initial gas, refueled gas, and gas consumed during the trip, we can accurately determine the remaining gallons of gas in Royston's car at any point during the journey.
