Okay, you do the same thing as last time. You add 10 + 15 + 13 + 15 + 22 = 75. Since the Sedan get 20 miles per gallon and there is 5 gallons left in the tank, you multiply 5 and 20. So, 5 x 20 = 100. So, 100 - 75= 25. After making the trip you can still have enough gas to go another 25 miles. Meaning, you do have enough gas to make the trip. :) Have a nice day!!
