Shana (from question 3) took her Porsche for a drive on the Parkway. She used 4.55 gallons of the gas she bought. How much gas does Shana have left?

Let's say Shana initially filled her tank with 15 gallons of gas. If she used 4.55 gallons for her delightful drive, the calculation to find out how much she has left is simply subtracting the amount used from the total. So, 15 gallons - 4.55 gallons equals 10.45 gallons. Therefore, Shana has 10.45 gallons of gas left to fuel her next adventure! Just remember, if you're ever calculating gas usage, always keep an eye on your mileage as well! Running low on fuel while enjoying a scenic drive can turn an exhilarating experience into a not-so-fun situation. Make sure to plan your drives and refuel before hitting the road!
