Rotating is driving to a popular amusement park with his family. Royston's car had 15th 1/5 gallons of gas at the start of the trip. During the trip, he stopped at a gas station and refueled his car with 5 3/5 gallons. If the car consumed 17 4/5 gallons of gas during the trip, there are still how many gallons of gas remaining in the tank?

Final answer:

There are 0 gallons of gas remaining in the tank.

Step-by-step explanation:

To find out how many gallons of gas are remaining in the tank, we need to subtract the total amount of gas consumed during the trip from the initial amount of gas in the tank.

Initial amount of gas: 15 1/5 gallons

Gas refueled during the trip: 5 3/5 gallons

Gas consumed during the trip: 17 4/5 gallons

To subtract mixed numbers, we need to convert them to improper fractions:

Initial amount of gas: 15 1/5 gallons = 15 + 1/5 = 75/5 + 1/5 = 76/5 gallons

Gas refueled during the trip: 5 3/5 gallons = 5 + 3/5 = 25/5 + 3/5 = 28/5 gallons

Gas consumed during the trip: 17 4/5 gallons = 17 + 4/5 = 85/5 + 4/5 = 89/5 gallons

Now, subtract the gas consumed from the initial amount of gas:

Gas remaining = Initial amount of gas - Gas consumed during the trip = 76/5 - 89/5 = (76 - 89)/5 = -13/5 gallons

Since we can't have a negative amount of gas remaining, the answer is 0 gallons of gas remaining in the tank.
